[PATCH v5 00/11] xfs: introduce the free inode btree

[Brian Foster <bfoster@redhat.com>]

Hi all,

This is a minor rebase of the finobt series on the latest for-next
branch. The previous version (v4) is here:

The most recent series with review feedback is v3:

v5:
- Rebase to latest for-next.
v4:
- Fixed up comments associated with separation of the AGI into separate
  logging regions.
- Added warning on ENOSPC failure of ifree reservation and comment
  describing reasoning for ifree being reserve-enabled.
- Removed finobt res. from xfs_calc_create_resv_alloc() (v4 sb only).
- Updated xfs_calc_finobt_res() to account for free space btrees and
  enable for inode alloc. record modification scenario.
- Renamed xfs_dialloc_ag_slow() to xfs_dialloc_ag_inobt().
- Refactored the inode allocation algorithm into several smaller helper
  functions.
- Fixed up comments in xfs_difree_finobt().
v3:
- Rebased to latest master.
- Fixed up unused variable warning in xfs_difree_inobt().
- Replaced a few more typedefs.
v2:
- Rebase to latest xfs tree (minor shifting around of some header bits).
- Added "xfs: report finobt status in fs geometry" patch to series.
v1:
- Separate patch to enable rw finobt support at end of series.
- Rework xfs_ialloc_log_agi() to log the agi in two distinct regions.
- Rework xfs_ialloc_btree.c changes to use separate finobt handlers
  where appropriate.
- Fix bug to show fibt2 stats data in stat proc file.
- Move finobt log reservation calculations into separate helper, made
  conditional and merged to a single patch.
- Use reserved block pool in xfs_inactive() codepath instead of flush.
- Moved and cleaned up xfs_inobt_insert() to use inobt helpers.
- Enhanced lookup algorithm for allocation (xfs_dialloc_ag()).
- Refactored xfs_difree() to use xfs_difree_inobt() and
  xfs_difree_finobt(), cleaned up the latter.

  xfs: update inode allocation/free transaction reservations for finobt
  xfs: insert newly allocated inode chunks into the finobt
  xfs: use and update the finobt on inode allocation
  xfs: refactor xfs_difree() inobt bits into xfs_difree_inobt() helper
  xfs: update the finobt on inode free
  xfs: add finobt support to growfs
  xfs: report finobt status in fs geometry
  xfs: enable the finobt feature on v5 superblocks
