This series simplifies how the CRC32 library functions are exposed through the crypto_shash API. We'll now have just one shash algorithm each for "crc32" and "crc32c", and their driver names will just always be "crc32-lib" and "crc32c-lib" respectively. This seems to be all that's actually needed. As mentioned in patch 2, this does change the content of /sys/fs/btrfs/$uuid/checksum again, but that should be fine. This is based on v6.16-rc1, and I'm planning to take these patches through the crc-next tree. These supersede https://lore.kernel.org/r/20250601224441.778374-2-ebiggers@xxxxxxxxxx/ and https://lore.kernel.org/r/20250601224441.778374-3-ebiggers@xxxxxxxxxx/, and they fix the warning in the full crypto self-tests reported at https://lore.kernel.org/r/aExLZaoBCg55rZWJ@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/ Eric Biggers (2): btrfs: stop parsing crc32c driver name crypto/crc32[c]: register only "-lib" drivers crypto/Makefile | 2 -- crypto/crc32.c | 65 +++++---------------------------------------- crypto/crc32c.c | 66 ++++------------------------------------------ crypto/testmgr.c | 2 ++ fs/btrfs/disk-io.c | 8 ++---- 5 files changed, 15 insertions(+), 128 deletions(-) base-commit: 19272b37aa4f83ca52bdf9c16d5d81bdd1354494 -- 2.49.0
