This series includes fixes based on review of v3: http://oss.sgi.com/archives/xfs/2014-02/msg00121.html The primary changes in v4 are fixes to the transaction reservation calculations for inode management, a refactoring of the finobt-based inode allocation algorithm into smaller helper functions and the addition of a warning in the unlikely scenario of reserve block pool exhaustion due to ifree transactions (inode eviction). Minor fixes and comment cleanups are included as requested in review for v3. Thoughts, reviews and flames appreciated. Brian 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.
