[v3,00/12] btrfs-progs: support xxhash64 checksums

Message

Johannes Thumshirn Aug. 30, 2019, 11:32 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.

For changes since v2, please see the individual patches. Additionally a patch
moving the CRC32C implementation from kernel-lib/ to crypto/ was added.

For changes since v1, please see the individual patches. Additionally a unit
test was added for regression testing this series.

David Sterba (3):
  btrfs-progs: update checksumming api
  btrfs-progs: add xxhash sources
  btrfs-progs: add xxhash64 as checksum algorithm

Johannes Thumshirn (9):
  btrfs-progs: don't blindly assume crc32c in csum_tree_block_size()
  btrfs-progs: cache csum_type in recover_control
  btrfs-progs: add checksum type to checksumming functions
  btrfs-progs: don't assume checksums are always 4 bytes
  btrfs-progs: pass checksum type to
    btrfs_csum_data()/btrfs_csum_final()
  btrfs-progs: simplify update_block_csum() in btrfs-sb-mod.c
  btrfs-progs: add option for checksum type to mkfs
  btrfs-progs: move crc32c implementation to crypto/
  btrfs-progs: add test-case for mkfs with xxhash64
