This patch adds write support to the uninitialized extents that get
created when a preallocation is done using fallocate(). It takes care of
splitting the extents into multiple (upto three) extents and merging the
new split extents with neighbouring ones, if possible.

This patch implements ->fallocate() inode operation in ext4. With this
patch users of ext4 file systems will be able to use fallocate() system
call for persistent preallocation.
Current implementation only supports preallocation for regular files
(directories not supported as of date) with extent
This patch adds a check for overlap of extents and cuts short the
new extent to be inserted, if there is a chance of overlap.

Fix AFS to write back dirty on unmounting. This didn't happen because
afs_super_ops.drop_inode was pointing to generic_delete_inode. Now this
pointer is left set to NULL so that the default behaviour occurs instead.

Hi,
Thanks for report. It seems like a lockdep problem. i_mutex for quota
