[RFC,0/4] Support xxhash64 checksums

Message

Johannes Thumshirn July 25, 2019, 9:33 a.m. UTC

Now that Nikolay's XXHASH64 support for the Crypto API has landed and BTRFS is
prepared for an easy addition of new checksums, this patchset implements
XXHASH64 as a second, fast but not cryptographically secure checksum hash.

This still is in RFC state (especially the btrfs-progs side).

David Sterba (1):
  btrfs: sysfs: export supported checksums

Johannes Thumshirn (3):
  btrfs: turn checksum type define into a union
  btrfs: create structure to encode checksum type and length
  btrfs: use xxhash64 for checksumming
