Hi all, this series adds back delalloc support for RT inodes, at least if the RT extent size is a single file system block. This shows really nice performance improvements for workloads that frequently rewrite or append to files, and improves fragmentation for larger writes. On other workloads it sometimes shows small performance improvements or flat performance. Changes since v5: - rebased to current xfs for-next (aka fixed a trival conflict due to two #include statements added in the same place) Changes since v4: - fix a bug in the fix for splitting RT delalloc reservations - rework where rtbitmap locking happens in the bunmapi patch to avoid churn with a series in development, stealing a patch from Darrick's giant patch queue in the process Changes since v3: - fix a bug in splitting RT delalloc reservations - fix online repair of RT delalloc fscounters - adjust the freespace counter refactoing to play nicer with an upcoming series of mine Changes since v3: - drop gratuitous changes to xfs_mod_freecounter/xfs_add_freecounter that caused a warning to be logged when it shouldn't. - track delalloc rtextents instead of rtblocks in xfs_mount - fix commit message spelling an typos Changes since v2: - keep casting to int64_t for xfs_mod_delalloc - add a patch to clarify and assert that the block delta in xfs_trans_unreserve_and_mod_sb can only be positive Diffstat: libxfs/xfs_ag.c | 4 - libxfs/xfs_ag_resv.c | 24 +------ libxfs/xfs_ag_resv.h | 2 libxfs/xfs_alloc.c | 4 - libxfs/xfs_bmap.c | 152 ++++++++++++++++++++++------------------------ libxfs/xfs_rtbitmap.c | 57 +++++++++++++++++ libxfs/xfs_rtbitmap.h | 17 +++++ libxfs/xfs_shared.h | 6 + scrub/common.c | 1 scrub/fscounters.c | 12 ++- scrub/fscounters.h | 1 scrub/fscounters_repair.c | 3 scrub/repair.c | 5 - xfs_fsmap.c | 4 - xfs_fsops.c | 29 ++------ xfs_fsops.h | 2 xfs_inode.c | 3 xfs_iomap.c | 44 +++++++++---- xfs_iops.c | 2 xfs_mount.c | 85 +++++++++++++++---------- xfs_mount.h | 36 ++++++++-- xfs_rtalloc.c | 22 ++---- xfs_super.c | 17 +++-- xfs_trace.h | 1 xfs_trans.c | 63 +++++++++---------- 25 files changed, 348 insertions(+), 248 deletions(-)
