For changes since v1, please see the individual patches. David Sterba (1): btrfs: sysfs: export supported checksums Johannes Thumshirn (3): btrfs: turn checksum type define into a enum btrfs: create structure to encode checksum type and length btrfs: use xxhash64 for checksumming fs/btrfs/Kconfig | 1 + fs/btrfs/ctree.h | 17 ++++++++++++----- fs/btrfs/disk-io.c | 1 + fs/btrfs/super.c | 1 + fs/btrfs/sysfs.c | 29 +++++++++++++++++++++++++++++ include/uapi/linux/btrfs_tree.h | 5 ++++- 6 files changed, 48 insertions(+), 6 deletions(-)
