Brian Behlendorf e92d6d861f Update linux-kernel-module with refreshed EXPORT_SYMBOLs
After such a large update many of the symbols which were previously
exported are no longer available, and several new symbols have been
added and are needed.  Refresh to topic branch to reflect this.

Brian Behlendorf 3a0400ad88 Update linux-events
Minor updates to linux-events to handle some upstream changes.  Luckily,
this was done flexibly enough the first time it wasn't much of a problem.

Brian Behlendorf c7068a5d76 Merge branch 'linux-kernel-mem' into refs/top-bases/linux-zfs-branch 2010-05-20 10:25:20 -07:00
Brian Behlendorf 4ae64a8acd 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.

Brian Behlendorf feb723fa7d Merge branch 'linux-events' into refs/top-bases/linux-zfs-branch 2010-05-14 12:55:10 -07:00
Brian Behlendorf 97d19a5e45 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.

$ sudo cmd/zpool/zpool events -fv
TIME                        CLASS
May 13 2010 16:31:15.777711000 ereport.fs.zfs.config.sync
        class = "ereport.fs.zfs.config.sync"
        ena = 0x40982b7897700001
        detector = (embedded nvlist)
                version = 0x0
                scheme = "zfs"
                pool = 0xed976600de75dfa6
        (end detector)

        time = 0x4bec8bc3 0x2e5aed98
        pool = "zpios"
        pool_guid = 0xed976600de75dfa6
        pool_context = 0x0

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

Brian Behlendorf f1d99c0653 Revert to original debugging code and wrap any variabled used only
within an ASSERT with the ASSERTV macro which will ensure it will
be removed when the ASSERTs are commented out.  This makes gcc much
happier, makes the variables usage explicit, and removes the need
for the compiler to detect it is unused and do the right thing.
