Subject: btrfs: remove btrfs_bio_end_io_t
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7b41ba71c1a08ae35805b562ae5e2f8ddfb8e00d;p=linux.git

btrfs: remove btrfs_bio_end_io_t

The btrfs_bio_end_io_t typedef was introduced with commit
a1d3c4786a4b ("btrfs: btrfs_multi_bio replaced with btrfs_bio")
but never used anywhere. This commit also introduced a forward declaration
of 'struct btrfs_bio' which is only needed for btrfs_bio_end_io_t.

Remove both as they're not needed anywhere.
