Fri, 30 Jan 2026 01:11:22 +0100

btrfs: tests: add unit tests for pending extent walking functionsI ran into another sort of trivial bug in v1 of the patch and concludedthat these functions really ought to be unit tested.These two functions form the core of searching the chunk allocationpending extent bitmap and have relatively easily definable semantics, sounit testing them can help ensure the correctness of chunk allocation.I also made a minor unrelated fix in volumes.h to properly forwarddeclare btrfs_space_info. Because of the order of the includes in thenew test, this was actually hitting a latent build warning.Note:This is an early example for me of a commit authored in part by an AIagent, so I wanted to more clear about what I did. I defined atrivial test and explained the set of tests I wanted to the agent and itproduced the large set of test cases seen here. I then checked each testcase to make sure it matched the description and simplified theconstants and numbers until they looked reasonable to me. I then checkedthe looping logic to make sure it made sense to the original spirit ofthe trivial test. Finally, carefully combed over all the lines it wroteto loop over the tests it generated to make sure they followed our codestyle guide.Assisted-by: Claude:claude-opus-4-5Signed-off-by: Boris Burkov Signed-off-by: David Sterba List of files: /linux/fs/btrfs/Makefile

Thu, 14 Nov 2024 16:03:34 +0100

btrfs: selftests: add delayed ref self test casesThe recent fix for a stupid mistake I made uncovered the fact that wedon't have adequate testing in the delayed refs code, as it took apretty extensive and long running stress test to uncover something thata unit test would have uncovered right away.Fix this by adding a delayed refs self test suite. This will validatethat the btrfs_ref transformation does the correct thing, that we do thecorrect thing when merging delayed refs, and that we get the delayedrefs in the order that we expect. These are all crucial to how thedelayed refs operate.I introduced various bugs (including the original bug) into the delayedrefs code to validate that these tests caught all of the shenanigansthat I could think of.Reviewed-by: Boris Burkov Signed-off-by: Josef Bacik Signed-off-by: David Sterba List of files: /linux/fs/btrfs/Makefile

Tue, 25 Jun 2024 16:52:28 +0200

btrfs: move the direct IO code into its own fileThe direct IO code is over a thousand lines and it's currently spreadbetween file.c and inode.c, which makes it not easy to locate some partsof it sometimes. Also inode.c is about 11 thousand lines and file.c about4 thousand lines, both too big. So move all the direct IO code into adedicated file, so that it's easy to locate all its code and reduce thesizes of inode.c and file.c.This is a pure move of code without any other changes except export aa couple functions from inode.c (get_extent_allocation_hint() andcreate_io_em()) because they are used in inode.c and the new direct-io.cfile, and a couple functions from file.c (btrfs_buffered_write() andbtrfs_write_check()) because they are used both in file.c and in the newdirect-io.c file.Reviewed-by: Boris Burkov Reviewed-by: Qu Wenruo Signed-off-by: Filipe Manana Signed-off-by: David Sterba List of files: /linux/fs/btrfs/Makefile

btrfs: move fiemap code into its own fileCurrently the core of the fiemap code lives in extent_io.c, which doesnot make any sense because it's not related to extent IO at all (and itwas not as well before the big rewrite of fiemap I did some time ago).The entry point for fiemap, btrfs_fiemap(), lives in inode.c since it'san inode operation.Since there's a significant amount of fiemap code, move all of it into adedicated file, including its entry point inode.c:btrfs_fiemap().Reviewed-by: Johannes Thumshirn Signed-off-by: Filipe Manana Reviewed-by: David Sterba Signed-off-by: David Sterba List of files: /linux/fs/btrfs/Makefile

Wed, 11 Jan 2023 12:36:13 +0100

btrfs: send: genericize the backref cache to allow it to be reusedThe backref cache is a cache backed by a maple tree and a linked list tokeep track of temporal access to cached entries (the LRU entry always atthe head of the list). This type of caching method is going to be usefulin other scenarios, so make the cache implementation more generic andmove it into its own header and source files.This patch is part of a larger patchset and the changelog of the lastpatch in the series contains a sample performance test and results.The patches that comprise the patchset are the following: btrfs: send: directly return from did_overwrite_ref() and simplify it btrfs: send: avoid unnecessary generation search at did_overwrite_ref() btrfs: send: directly return from will_overwrite_ref() and simplify it btrfs: send: avoid extra b+tree searches when checking reference overrides btrfs: send: remove send_progress argument from can_rmdir() btrfs: send: avoid duplicated orphan dir allocation and initialization btrfs: send: avoid unnecessary orphan dir rbtree search at can_rmdir() btrfs: send: reduce searches on parent root when checking if dir can be removed btrfs: send: iterate waiting dir move rbtree only once when processing refs btrfs: send: initialize all the red black trees earlier btrfs: send: genericize the backref cache to allow it to be reused btrfs: adapt lru cache to allow for 64 bits keys on 32 bits systems btrfs: send: cache information about created directories btrfs: allow a generation number to be associated with lru cache entries btrfs: add an api to delete a specific entry from the lru cache btrfs: send: use the lru cache to implement the name cache btrfs: send: update size of roots array for backref cache entries btrfs: send: cache utimes operations for directories if possibleSigned-off-by: Filipe Manana Reviewed-by: David Sterba Signed-off-by: David Sterba List of files: /linux/fs/btrfs/Makefile
