Subject: bring back RT delalloc support v4
Date: Mon, 25 Mar 2024 10:24:00 +0800 [thread overview]
Message-ID: <20240325022411.2045794-1-hch@lst.de> (raw)
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 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
