Changes since v4:
- rebased on to of the mapping validation fixes from Brian and me
- fix SEEK_DATA / SEEK_HOLE vs COW fork preallocations
- sample the always_cow value in a per-mount variable
- disable all preallocation, including in zero range and unshare
Changes since v3:
- spelling fixes
- improve argument naming and add a comment in xfs_reflink_allocate_cow
- trace the COW imap if allocating COW blocks
- collect a few reviewed-by tags from Darrick
Changes since v2:
- add a patch to remove xfs_trim_extent_eof
- add a patch to remove the separate io_type and rely on existing state
in the writeback path
- rework the truncate race handling in the writeback path a little more
Changes since v1:
- make delalloc and unwritten extent conversions simpler and more robust
- add a few additional cleanups
- support all fallocate modes but actual preallocation
- rebase on top of a fix from Brian (which is included as first patch
to make the patch set more usable)
