Use __blk_end_request() in zvol_request() to avoid ZVOL deadlock.
...
The unlocked version of blk_end_request() should be used in the
zvol_request() error handling to avoid deadlocking the request_queue
queue_lock. Things get a little more complicated for older kernel
APIs but the compat layer has been updated as well to reflect this.

Recreate volume and snapshot /dev links during module load.
...
Links in /dev for volumes/snapshots were only being created
at volume/snapshot creation time. Those links are now also
created dynamically at module load time based on the spa config.
In other words all you need to do to get access to your zfs
datasets after a reboot is load the module. It's magic!

Move from kmem_alloc() to vmem_alloc().
...
These two allocations are 16k in size which trips the SPL warning
about large kmem_allocs(). For now simply shift them to a vmem_alloc().
Yes, this has it's own set of problems but this happens infrequently
enough not to be a real issue. But more importantly it means that
we've flagged this place in the code via this topic branch as a
place which still needs long term work.

Add linux-events topic branch for zevent handling.
...
This topic branch leverages the Solaris style FMA call points
in ZFS to create a user space visible event notification system
under Linux. This new system is called zevent and it unifies
all previous Solaris style ereports and sysevent notifications.
Under this Linux specific scheme when a sysevent or ereport event
occurs an nvlist describing the event is created which looks almost
exactly like a Solaris ereport. These events are queued up in the
kernel when they occur and conditionally logged to the console.
It is then up to a user space application to consume the events
and do whatever it likes with them.
To make this possible the existing /dev/zfs ABI has been extended
with two new ioctls which behave as follows.
* ZFS_IOC_EVENTS_NEXT
Get the next pending event. The kernel will keep track of the last
event consumed by the file descriptor and provide the next one if
available. If no new events are available the ioctl() will block
waiting for the next event. This ioctl may also be called in a
non-blocking mode by setting zc.zc_guid = ZEVENT_NONBLOCK. In the
non-blocking case if no events are available ENOENT will be returned.
It is possible that ESHUTDOWN will be returned if the ioctl() is
called while module unloading is in progress. And finally ENOMEM
may occur if the provided nvlist buffer is not large enough to
contain the entire event.
* ZFS_IOC_EVENTS_CLEAR
Clear are events queued by the kernel. The kernel will keep a fairly
large number of recent events queued, use this ioctl to clear the
in kernel list. This will effect all user space processes consuming
events.
The zpool command has been extended to use this events ABI with the
'events' subcommand. You may run 'zpool events -v' to output a
verbose log of all recent events. This is very similar to the
Solaris 'fmdump -ev' command with the key difference being it also
includes what would be considered sysevents under Solaris. You
may also run in follow mode with the '-f' option. To clear the
in kernel event queue use the '-c' option.

While the 'zpool events' command is handy for interactive debugging
it is not expected to be the primary consumer of zevents. This ABI
was primarily added to facilitate the addition of a user space
monitoring daemon. This daemon would consume all events posted by
the kernel and based on the type of event perform an action. For
most events simply forwarding them on to syslog is likely enough.
But this interface also cleanly allows for more sophisticated
actions to be taken such as generating an email for a failed drive

Create linux-kernel-device topic branch.
...
This branch contains the majority of the changes required to cleanly
intergrate with Linux style special devices (/dev/zfs). Mainly this
means dropping all the Solaris style callbacks and replacing them
with the Linux equivilants. Additionally, this means slightly
expanding the zfs_ioc_* functions to include a 'struct file *' to
allow the tracking of private data for each open file descriptor.
This is very helpful when you need to maintain a little information
about the open file between ioctls().

Revert zfs_ioctl.c related changes.

All the changes required to cleanly integrate with linux style
devices are being moved to their own topic branch. It was abouti
to get to the point where too many topic branches each wanted to
tweak this code and it was getting confusing. To simplify this
all /dev/zfs device related changes are being moved to the
linux-kernel-device topic branch.

Fix struct ht_lock padding in arc.c.
...
This was leading to a compilation error because in Linux, sizeof
(kmutex_t) can be larger than 64 in some circumstances (e.g. with
debugging and lockdep enabled).
The code was previously fixed to align the structure to 256 bytes,
but a better fix is to align it to the next multiple of 64 bytes.

Include all headers regardless of depth
...
The previous hack for this was to move headers 3 levels deep in to
the top level include dir and headers 4 levels deep in to sys.
Obviously this was fairly limiting and missed two important headers.
./zfs/include/sys/fm/fs/zfs.h
./zfs/include/sys/fs/zfs.h
This patch updates the code to be smarter and installs all the headers
to the correct location regardless of depth. Each header will have its
leading 3 path args stripped (i.e. ./zfs/include/) and replaced with
the correct install destination. All path information past the first
three levels will be preserved.

No inline to keep dmu_recv_stream() stack frame less than 1024 bytes.
...
Recent builds against 2.6.31 flagged dmu_recv_stream() as stack heavy.
As a quick simple way to resolve this I'm preventing the inlining of
certain functions which gcc will inline here because this is the only
place they are called. Futher analysis of this function should be
performed to futher reduce its stack usage.

Linux ZVOL implementation; kernel-side changes
...
At last a useful user space interface for the Linux ZFS port arrives.
With the addition of the ZVOL real ZFS based block devices are available
and can be compared head to head with Linux's MD and LVM block drivers.
The Linux ZVOL has not yet had any performance work done but from a user
perspective it should be functionally complete and behave like any other
Linux block device.
The ZVOL has so far been tested using zconfig.sh on the following x86_64
based platforms: FC11, CHAOS4, RHEL5, RHEL6, and SLES11. However, more
testing is required to ensure everything is working as designed.
What follows in a somewhat detailed list of changes includes in this
commit to make ZVOL's possible. A few other issues were addressed in
the context of these changes which will also be mentioned.
* Added module/zfs/zvol.c which is based off the original Solaris ZVOL
implementation but rewritten to intergrate with the Linux block device
APIs. The basic design remains the similar in Linux with the major
change being request processing. Request processing is handled by
registering a request function which the elevator calls once all request
merges is finished and the elevator unplugs. This function is called
under a spin lock and the request structure is passed to the block driver
to be queued for IO. The elevator must be notified asyncronously once
the request completes or fails with an error. This allows us the block
driver a chance to handle many request concurrently. For the ZVOL we
maintain a taskq with a service thread per core. As requests are delivered
by the elevator each request is dispatched to the taskq. The task queue
handles each request with a write or read helper function which basically
copies the request data in to our out of the DMU object. Writes single
completion as soon as the DMU has the data unless they are marked sync.
Reads are all handled syncronously however the elevator will merge many
small reads in to a large read before it submitting the request.
* Cachine is worth specifically mentioning. Because both the Linux VFS
and the ZFS ARC both want to fully manage the cache we unfortunately
end up with two caches. This means our memory foot print is larger
than otherwise expected, and it means we have an extra copy between
the caches, but it does not impact correctness. All syncs are barrior
requests I believe are handled correctly. Longer term there is lots of
room for improvement here but it will require fairly extensive changes
to either the Linux VFS and VM layer, or additional DMU interfaces to
handle managing buffer not directly allocated by the ARC.
* Added module/zfs/include/sys/blkdev.h which contains all the Linux
compatibility foo which is required to handle changes in the Linux block
APIs from 2.6.18 thru 2.6.31 based kernels.
* The dmu_{read,write}_uio interfaces which don't make sense on Linux
have been modified to dmu_{read,write}_req functions which consume the
standard Linux IO request structure. Their function fundamentally
remains the same so this happily worked out pretty cleanly.
* The /dev/zfs character device is no longer created through the half
implemented Solaris driver DDI interfaces. It is now simply created
with it's own major number as a Linux misc device which greatly simplifies
everything. It is only capable of handling ioctls() but this fits nicely
because that's all it ever has to do. The ZVOL devices unlike in Solaris
do not leverage the same major number as /dev/zfs but instead register
their own major. Because only one major is allocated and space is reserved
for 16 partitions per-device there is a limit of 16384 concurrent ZVOL
devices. By using multiple majors like the scsi driver this limit could
be addressed if it becomes a problem.
* The {spa,zfs,zvol}_busy() functions have all be removed because they
are not required on a Linux system. Under Linux the registered module
exit function will not be called while the are still references to the
module. Once the exit function is called however it must succeed or
block, it may not fail so returning an error on module unload makes to
sense under Linux.
* With the addition of ZVOL support all the HAVE_ZVOL defines were removed
for obvious reasons. However, the HAVE_ZPL defines have been relocated
in to the linux-{kernel,user}-disk topic branches and must remain until
the ZPL is implemented.

Adds the last missing block device support (merge_bdev support)
...
This change should wrap up the last of the missing block device
support in the vdev_disk layer. With this change I can now
successfully create and use zpools which are layered on top of
md and lvm virtual devices. The following changes include:
1) The big one, properly handle the case when page cannot be added
to a bio due to dynamic limitation of a merge_bdev handler. For
example the md device will limit a bio to the configured stripe
size. Our bio size may also end up being limited by the maximum
request size, and other factors determined during bio construction.
To handle all of the above cases the code has been updated to
handle failures from bio_add_page(). This had been hardcoded to
never fail for the prototype proof of concept implementation. In
the case of a failure the number of bytes which still need to be
added to a bio are returned. New bio's are allocated and attached
to the dio until the entire data buffer is mapped to bios. It is
then submitted as before to the request queue, and once all the bio's
attached to a dio have finished the completion callback is run.
2) The devid comments have been removed because it is not clear to
me that we will not need devid support. They have been replaced
with a comment explaining that udev can and should be used.

Fix sector size and capacity calculation.

Remove the hard coded 512 byte SECTOR_SIZE and replace it with
bdev_hardsect_size() to get the correct hardware sector size.
Usage of get_capacity() was incorrect. We the block_device
references a partition we need to return bdev->part->nr_sects.
If get_capacity() is used the entire device size will be returned
ignoring partition information. This is however the correct thing
to do when the block device in question has not partition table.

As of 2.6.25 kobj->k_name was replaced with kobj->name. Some distros
such as RHEL5 (2.6.18) add a patch to prevent this from being a problem
but other older distros such as SLES10 (2.6.16) have not. To avoid
the whole issue I'm updating the code to use kobject_set_name() which
does what I want and has existed all the way back to 2.6.11.

Extra reference required for dio struct in __vdev_disk_physio.
...
Exposed by the fc11 debug kernel we need to hold a reference over all
calls to submit_bio(). Otherwise it is possible all the completion
callbacks run before we exit __vdev_disk_physio(), and we end up with
a GPF. This was quickly exposed when slab poisoning was enabled. I
have added helper functions to cleanly track the reference counts. In
addition dr->dr_ref was converted from an integer to an atomic type
which removes the need for the spinlock. As a nice side effect of
these changes the code is now slightly cleaner and clearer.
