[PATCH 0/2] fix up indlen reservations on extent split

[Brian Foster]

Hi all,

Here's a couple patches to fix up the indirect block reservation
problem when splitting delalloc extents, described in more detail in the
patch 2 commit log.

This runs through xfstests without any explosions and quiets down
generic/033 when used in combination with the zero range rework (current
for-next includes the writeback on zero range workaround that also
prevents generic/033 asserts).

v1:
- xfs_bunmapi() code into independent patch.
- Refactor fix into separate helper function.

Brian Foster (2):
  xfs: update icsb freeblocks counter after extent deletion
  xfs: borrow indirect blocks from freed extent when available
