Wed, 07 Jan 2026 15:09:08 +0100

btrfs: allow mounting filesystems with remap-tree incompat flagIf we encounter a filesystem with the remap-tree incompat flag set,validate its compatibility with the other flags, and load the remap treeusing the values that have been added to the superblock.The remap-tree feature depends on the free-space-tree, but no-holes andblock-group-tree have been made dependencies to reduce the testingmatrix. Similarly I'm not aware of any reason why mixed-bg and zoned would beincompatible with remap-tree, but this is blocked for the time beinguntil it can be fully tested.Reviewed-by: Boris Burkov Signed-off-by: Mark Harmstone Signed-off-by: David Sterba List of files: /linux/fs/btrfs/Kconfig

Thu, 08 Jan 2026 05:01:03 +0100

btrfs: remove experimental offload csum modeThe offload csum mode was introduced to allow developers to compare theperformance of generating checksum for data writes at different timings:- During btrfs_submit_chunk() This is the most common one, if any of the following condition is met we go this path: * The csum is fast For now it's CRC32C and xxhash. * It's a synchronous write * Zoned- Delay the checksum generation to a workqueueHowever since commit dd57c78aec39 ("btrfs: introducebtrfs_bio::async_csum") we no longer need to bother any of them.As if it's an experimental build, async checksum generation at thebackground will be faster anyway.And if not an experimental build, we won't even have the offload csummode support.Considering the async csum will be the new default, let's remove theoffload csum mode code.There will be no impact to end users, and offload csum mode is stillunder experimental features.Signed-off-by: Qu Wenruo Reviewed-by: David Sterba Signed-off-by: David Sterba List of files: /linux/fs/btrfs/Kconfig

fe11ac191ce0ad910f6fda0c628bcff19fcff47d - btrfs: switch to library APIs for checksums

Fri, 05 Dec 2025 08:04:54 +0100

btrfs: switch to library APIs for checksumsMake btrfs use the library APIs instead of crypto_shash, for allchecksum computations. This has many benefits:- Allows future checksum types, e.g. XXH3 or CRC64, to be more easily supported. Only a library API will be needed, not crypto_shash too.- Eliminates the overhead of the generic crypto layer, including an indirect call for every function call and other API overhead. A microbenchmark of btrfs_check_read_bio() with crc32c checksums shows a speedup from 658 cycles to 608 cycles per 4096-byte block.- Decreases the stack usage of btrfs by reducing the size of checksum contexts from 384 bytes to 240 bytes, and by eliminating the need for some functions to declare a checksum context at all.- Increases reliability. The library functions always succeed and return void. In contrast, crypto_shash can fail and return errors. Also, the library functions are guaranteed to be available when btrfs is loaded; there's no longer any need to use module softdeps to try to work around the crypto modules sometimes not being loaded.- Fixes a bug where blake2b checksums didn't work on kernels booted with fips=1. Since btrfs checksums are for integrity only, it's fine for them to use non-FIPS-approved algorithms.Note that with having to handle 4 algorithms instead of just 1-2, thiscommit does result in a slightly positive diffstat. That being said,this wouldn't have been the case if btrfs had actually checked forerrors from crypto_shash, which technically it should have been doing.Reviewed-by: Ard Biesheuvel Reviewed-by: Neal Gompa Signed-off-by: Eric Biggers Reviewed-by: David Sterba Signed-off-by: David Sterba List of files: /linux/fs/btrfs/Kconfig
