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@kernel.org/
and
https://lore.kernel.org/r/20250601224441.778374-3-ebiggers@kernel.org/,
and they fix the warning in the full crypto self-tests reported at
https://lore.kernel.org/r/aExLZaoBCg55rZWJ@li-008a6a4c-3549-11b2-a85c-c5cc2836eea2.ibm.com/

Eric Biggers (2):
  btrfs: stop parsing crc32c driver name
  crypto/crc32[c]: register only "-lib" drivers
