This patch aims to replace kmem_zalloc_large() with global kernel memory
API. So, all its callers are now using kvzalloc() directly, so kmalloc()
fallsback to vmalloc() automatically.Signed-off-by: Carlos Maiolino

Enable the bigtime feature for quota timers. We decrease the accuracy
of the timers to ~4s in exchange for being able to set timers up to the

Redesign the ondisk inode timestamps to be a simple unsigned 64-bit
counter of nanoseconds since 14 Dec 1901 (i.e. the minimum time in the
32-bit unix time epoch). This enables us to handle dates up to 2486,
which solves the y2038 problem.Signed-off-by: Darrick J. Wong

The log recovery I/O completion handler does not substancially differ from
the normal one except for the fact that it:a) never retries failed writes
b) can have log items that aren't on the AIL
c) never has inode/dquot log items attached and thus don't need to
handle themAdd conditionals for (a) and (b) to the ioend code, while (c) doesn't
need special handling anyway.Signed-off-by: Christoph Hellwig

Now that all the actual error handling is in a single place,
xfs_buf_ioend_disposition just needs to return true if took ownership of

the function a better fitting name.Signed-off-by: Christoph Hellwig

With the recent rework of the inode cluster flushing, we no longer
ever wait on the the inode flush "lock". It was never a lock in the
first place, just a completion to allow callers to wait for inode IO
to complete. We now never wait for flush completion as all inode
flushing is non-blocking. Hence we can get rid of all the iflock
infrastructure and instead just set and check a state flag.Rename the XFS_IFLOCK flag to XFS_IFLUSHING, convert all the
xfs_iflock_nowait() test-and-set operations on that flag, and
replace all the xfs_ifunlock() calls to clear operations.Signed-off-by: Dave Chinner
