Hi all, Here's a v6 of sparse inode chunks. This fixes a bug on large block size filesystems where an inode chunk was being incorrectly freed. The problem was that patch 2 changed the previously implicit behavior of never freeing an inode chunk on filesystems where the block size is large enough for multiple chunks (e.g., bsize=64k, isize<=512). Patch 2 has been fixed to preserve original behavior. There have also been some minor fixups throughout associated with a rebase to the latest for-next. This includes killing some old sb logging bits and passing mp to XFS_WANT_CORRUPTED_GOTO(). Brian v6: - Rebase to latest for-next (minor fixups). - Fix corruption bug on multi-inode-chunk per block fs (patch 2). v5: http://oss.sgi.com/archives/xfs/2015-02/msg00371.html - Use XFS helpers for allocmask code instead of generic bitmap helpers. v4: http://oss.sgi.com/archives/xfs/2015-02/msg00240.html - Rename sb_spinoalignmt to sb_spino_align. - Clean up error/warning messages. - Use a union to differentiate old/new xfs_inobt_rec on-disk format. Refactor such that in-core record fields are always valid. - Rename/move allocmap (bitmap) helper functions and provide extra helper for endian conv. - Refactor sparse chunk allocation record management code. - Clean up #ifdef and label usage for DEBUG mode sparse allocs. - Split up and moved some generic, preparatory hunks earlier in series. v3: http://oss.sgi.com/archives/xfs/2015-02/msg00110.html - Rebase to latest for-next (bulkstat rework, data structure shuffling, etc.). - Fix issparse helper logic. - Update inode alignment model w/ spinodes enabled. All inode records are chunk size aligned, sparse allocations cluster size aligned (both enforced on mount). - Reworked sparse inode record merge logic to coincide w/ new alignment model. - Mark feature as experimental (warn on mount). - Include and use block allocation agbno range limit to prevent allocation of invalid inode records. - Add some DEBUG bits to improve sparse alloc. test coverage. v2: http://oss.sgi.com/archives/xfs/2014-11/msg00007.html - Use a manually set feature bit instead of dynamic based on the existence of sparse inode chunks. - Add sb/mp fields for sparse alloc. granularity (use instead of cluster size). - Undo xfs_inobt_insert() loop removal to avoid breakage of larger page size arches. - Rename sparse record overlap helper and do XFS_LOOKUP_LE search. - Use byte of pad space in inobt record for inode count field. - Convert bitmap mgmt to use generic bitmap code. - Rename XFS_INODES_PER_SPCHUNK to XFS_INODES_PER_HOLEMASK_BIT. - Add fs geometry bit for sparse inodes. - Rebase to latest for-next (bulkstat refactor). v1: http://oss.sgi.com/archives/xfs/2014-07/msg00355.html Brian Foster (18): xfs: create individual inode alloc. helper xfs: update free inode record logic to support sparse inode records xfs: support min/max agbno args in block allocator xfs: add sparse inode chunk alignment superblock field xfs: use sparse chunk alignment for min. inode allocation requirement xfs: sparse inode chunks feature helpers and mount requirements xfs: add fs geometry bit for sparse inode chunks xfs: introduce inode record hole mask for sparse inode chunks xfs: use actual inode count for sparse records in bulkstat/inumbers xfs: pass inode count through ordered icreate log item xfs: handle sparse inode chunks in icreate log recovery xfs: helper to convert holemask to inode alloc. bitmap xfs: allocate sparse inode chunks on full chunk allocation failure xfs: randomly do sparse inode allocations in DEBUG mode xfs: filter out sparse regions from individual inode allocation xfs: only free allocated regions of inode chunks xfs: skip unallocated regions of inode chunks in xfs_ifree_cluster() xfs: enable sparse inode chunks for v5 superblocks fs/xfs/libxfs/xfs_alloc.c | 42 ++- fs/xfs/libxfs/xfs_alloc.h | 2 + fs/xfs/libxfs/xfs_format.h | 48 +++- fs/xfs/libxfs/xfs_fs.h | 1 + fs/xfs/libxfs/xfs_ialloc.c | 541 +++++++++++++++++++++++++++++++++++---- fs/xfs/libxfs/xfs_ialloc.h | 12 +- fs/xfs/libxfs/xfs_ialloc_btree.c | 93 ++++++- fs/xfs/libxfs/xfs_ialloc_btree.h | 10 + fs/xfs/libxfs/xfs_sb.c | 30 ++- fs/xfs/xfs_fsops.c | 4 +- fs/xfs/xfs_inode.c | 28 +- fs/xfs/xfs_itable.c | 13 +- fs/xfs/xfs_log_recover.c | 26 +- fs/xfs/xfs_mount.c | 16 ++ fs/xfs/xfs_mount.h | 2 + fs/xfs/xfs_trace.h | 47 ++++ 16 files changed, 829 insertions(+), 86 deletions(-) -- 1.9.3 _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
