[PATCH 0/4] clean up collapse range and handle post-eof delalloc

[Brian Foster <bfoster@redhat.com>]

Hi all,

Here's a new drop of the patches that tweak collapse to be fsb based and
organize the code a bit. This has seen ~1.5b fsx ops without a failure
and some light xfstests testing so far.

The primary difference from this version and the rfc is the retention of
the eofblocks trim prior to collapse. Patch 4 is also new. It isolates
the pagecache writeback/truncate in xfs_free_file_space() to the range
affected by the free. Thoughts, reviews, flames appreciated.

Brian

v1:
- Retain the eofblocks trim and writeback/inval. the range of shifted
  data only.
- Added the xfs_free_file_space() patch to no longer writeback the
  entire file.
rfc: http://oss.sgi.com/archives/xfs/2014-08/msg00462.html

Brian Foster (4):
  xfs: track collapse via file offset rather than extent index
  xfs: refactor xfs_bmap_shift_extents() into multiple functions
  xfs: writeback and inval. file range to be shifted by collapse
  xfs: only writeback and truncate pages for the freed range
