Subject: [RFC PATCH 0/4] Support xxhash64 checksums
Date: Thu, 25 Jul 2019 11:33:47 +0200	[thread overview]
Message-ID: <cover.1564046812.git.jthumshirn@suse.de> (raw)

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
