xfs: update for 3.6-rc1
Numerous cleanups and several bug fixes. Here are some highlights:
* Discontiguous directory buffer support
* Inode allocator refactoring
* Removal of the IO lock in inode reclaim
* Implementation of .update_time
* Fix for handling of EOF in xfs_vm_writepage
* Fix for races in xfsaild, and idle mode is re-enabled
* Fix for a crash in xfs_buf completion handlers on unmount.
xfs: wait for the write the superblock on unmount
v2: Add the xfs_buf_lock to xfs_quiesce_attr().
Add explaination why xfs_buf_lock() is used to wait for write.
xfs_wait_buftarg() does not wait for the completion of the write of the
uncached superblock. This write can race with the shutdown of the log
and causes a panic if the write does not win the race.
During the log write, xfsaild_push() will lock the buffer and set the
XBF_ASYNC flag. Because the XBF_FLAG is set, complete() is not performed
on the buffer's iowait entry, we cannot call xfs_buf_iowait() to wait
for the write to complete. The buffer's lock is held until the write is
complete, so we can block on a xfs_buf_lock() request to be notified
that the write is complete.
