Due to the confusion in Linux statfs between f_frsize and f_bsize
the blocks counts were changed to be in units of z_max_blksize
instead of SPA_MINBLOCKSIZE as it is on other platforms.
However, the free files calculation in zfs_statvfs() is limited by
the free blocks count, since each dnode consumes one block/sector.
This provided a reasonable estimate of free inodes, but on Linux
this meant that the free inodes count was underestimated by a large
amount, since 256 512-byte dnodes can fit into a 128kB block, and
more if the max blocksize is increased to 1MB or larger.
Also, the use of SPA_MINBLOCKSIZE is semantically incorrect since
DNODE_SIZE may change to a value other than SPA_MINBLOCKSIZE and
may even change per dataset, and devices with large sectors setting
ashift will also use a larger blocksize.
Correct the f_ffree calculation to use (availbytes >> DNODE_SHIFT)
to more accurately compute the maximum number of dnodes that can
be created.

GPT's created by libefi set the HeaderSize attribute in the GPT
header to 512 -- size of the GPT header INCLUDING the 420 padding
bytes at the end. Most other tools set the size to 92 -- size of
the actual header itself excluding the padding. Most tools check
the recorded HeaderSize when verifying CRC, but gptfdisk hardcodes
92 and thus reports CRC verification problems for full-disk vdevs
created IE with `zpool create pool sdc`.
This commit changes libefi's behavior for GPT creation and also
fixes several edge cases where libefi's behavior was similar
(though in an incompatible manner) to gptfdisk. Libefi assumed
HeaderSize was always 512 even if the GPT recorded a different
value. Sanity checks of the GPT headersize read from disk were
added before applying checksum calculation -- this will prevent
segfault in cases of bogus on-disk values.
Zpools created with the resuling libefi are verified as correct
both by parted and gptfdisk. Also pool have been tested to
import correctly on ZFS on Linux as well as Solaris Express 11

Unlike the .readpage() callback which is passed a single locked page
to be populated. The .readpages() callback is passed a list of unlocked
pages which are all marked for read-ahead (PG_readahead set). It is
the responsibly of .readpages() to ensure to pages are properly locked
before being populated.
Prior to this change the requested read-ahead pages would be updated
outside of the page lock which is unsafe. The unlocked pages would then
be unlocked again which is harmless but should have been immediately
detected as bug. Unfortunately, newer kernels failed detect this issue
because the check is done with a VM_BUG_ON which is disabled by default.
Luckily, the old Debian Lenny 2.6.26 kernel caught this because it
simply uses a BUG_ON.
The straight forward fix for this is to update the .readpages() callback
to use the read_cache_pages() helper function. The helper function will
ensure that each page in the list is properly locked before it is passed
to the .readpage() callback. In addition resolving the bug, this results
in a nice simplification of the existing code.
The downside to this change is that instead of passing one large read
request to the dmu multiple smaller ones are submitted. All of these
requests however are marked for readahead so the lower layers should
issue a large I/O regardless. Thus most of the request should hit the
ARC cache.
Futher optimization of this code can be done in the future is a perform
analysis determines it to be worthwhile. But for the moment, it is
preferable that code be correct and understandable.

For a long time now the kernel has been moving away from using the
pdflush daemon to write 'old' dirty pages to disk. The primary reason
for this is because the pdflush daemon is single threaded and can be
a limiting factor for performance. Since pdflush sequentially walks
the dirty inode list for each super block any delay in processing can
slow down dirty page writeback for all filesystems.
The replacement for pdflush is called bdi (backing device info). The
bdi system involves creating a per-filesystem control structure each
with its own private sets of queues to manage writeback. The advantage
is greater parallelism which improves performance and prevents a single
filesystem from slowing writeback to the others.
For a long time both systems co-existed in the kernel so it wasn't
strictly required to implement the bdi scheme. However, as of
Linux 2.6.36 kernels the pdflush functionality has been retired.
Since ZFS already bypasses the page cache for most I/O this is only
an issue for mmap(2) writes which must go through the page cache.
Even then adding this missing support for newer kernels was overlooked
because there are other mechanisms which can trigger writeback.
However, there is one critical case where not implementing the bdi
functionality can cause problems. If an application handles a page
fault it can enter the balance_dirty_pages() callpath. This will
result in the application hanging until the number of dirty pages in
the system drops below the dirty ratio.
Without a registered backing_device_info for the filesystem the
dirty pages will not get written out. Thus the application will hang.
As mentioned above this was less of an issue with older kernels because
pdflush would eventually write out the dirty pages.
This change adds a backing_device_info structure to the zfs_sb_t
which is already allocated per-super block. It is then registered
when the filesystem mounted and unregistered on unmount. It will
not be registered for mounted snapshots which are read-only. This
change will result in flush-<pool> thread being dynamically created
and destroyed per-mounted filesystem for writeback.

Closes#174
While the existing implementation of .writepage()/zpl_putpage() was
functional it was not entirely correct. In particular, it would move
dirty pages in to a clean state simply after copying them in to the
ARC cache. This would result in the pages being lost if the system
were to crash enough though the Linux VFS believed them to be safe on
stable storage.
Since at the moment virtually all I/O, except mmap(2), bypasses the
page cache this isn't as bad as it sounds. However, as hopefully
start using the page cache more getting this right becomes more
important so it's good to improve this now.
This patch takes a big step in that direction by updating the code
to correctly move dirty pages through a writeback phase before they
are marked clean. When a dirty page is copied in to the ARC it will
now be set in writeback and a completion callback is registered with
the transaction. The page will stay in writeback until the dmu runs
the completion callback indicating the page is on stable storage.
At this point the page can be safely marked clean.
This process is normally entirely asynchronous and will be repeated
for every dirty page. This may initially sound inefficient but most
of these pages will end up in a few txgs. That means when they are
eventually written to disk they should be nicely batched. However,
there is room for improvement. It may still be desirable to batch
up the pages in to larger writes for the dmu. This would reduce
the number of callbacks and small 4k buffer required by the ARC.
Finally, if the caller requires that the I/O be done synchronously
by setting WB_SYNC_ALL or if ZFS_SYNC_ALWAYS is set. Then the I/O
will trigger a zil_commit() to flush the data to stable storage.
At which point the registered callbacks will be run leaving the
date safe of disk and marked clean before returning from .writepage.

The function txg_delay() is used to delay txg (transaction group)
threads in ZFS. The timeout value for this function is calculated
using:
int timeout = ddi_get_lbolt() + ticks;
Later, the actual wait is performed:
while (ddi_get_lbolt() < timeout &&
tx->tx_syncing_txg < txg-1 && !txg_stalled(dp))
(void) cv_timedwait(&tx->tx_quiesce_more_cv, &tx->tx_sync_lock,
timeout - ddi_get_lbolt());
The ddi_get_lbolt() function returns current uptime in clock ticks
and is typed as clock_t. The clock_t type on 64-bit architectures
is int64_t.
The "timeout" variable will overflow depending on the tick frequency
(e.g. for 1000 it will overflow in 28.855 days). This will make the
expression "ddi_get_lbolt() < timeout" always false - txg threads will
not be delayed anymore at all. This leads to a slowdown in ZFS writes.
The attached patch initializes timeout as clock_t to match the return
value of ddi_get_lbolt().

Prior to revision 11314 if a user was recursively destroying
snapshots of a dataset the target dataset was not required to
exist. The zfs_secpolicy_destroy_snaps() function introduced
the security check on the target dataset, so since then if the
target dataset does not exist, the recursive destroy is not
performed. Before 11314, only a delete permission check on
the snapshot's master dataset was performed.
Steps to reproduce:
zfs create pool/a
zfs snapshot pool/a@s1
zfs destroy -r pool@s1
Therefore I suggest to fallback to the old security check, if
the target snapshot does not exist and continue with the destroy.

Hypothesis about what's going on here.
At some time in the past, something, i.e. dnode_reallocate()
calls one of:
dbuf_rm_spill(dn, tx);
These will do:
dbuf_rm_spill(dnode_t *dn, dmu_tx_t *tx)
dbuf_free_range(dn, DMU_SPILL_BLKID, DMU_SPILL_BLKID, tx)
dbuf_undirty(db, tx)
Currently dbuf_undirty can leave a spill block in dn_dirty_records[],
(it having been put there previously by dbuf_dirty) and free it.
Sometime later, dbuf_sync_list trips over this reference to free'd
(and typically reused) memory.
Also, dbuf_undirty can call dnode_clear_range with a bogus
block ID. It needs to test for DMU_SPILL_BLKID, similar to
how dnode_clear_range is called in dbuf_dirty().
