Subject: btrfs: remove the disk_bytenr in struct btrfs_dio_private
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=acb8b52a158ae5610a1378f62de5ea061a12be3d;p=linux.git

btrfs: remove the disk_bytenr in struct btrfs_dio_private

This field is never used, so remove it. Last use was probably in
23ea8e5a0767 ("Btrfs: load checksum data once when submitting a direct
read io").
