X-Git-Tag: v4.19.90~118
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=dc2a320dc2a8d08c41ad304185efdf831d9c1f30;p=thirdparty%2Fkernel%2Fstable.git

btrfs: Remove btrfs_bio::flags member

commit 34b127aecd4fe8e6a3903e10f204a7b7ffddca22 upstream.

The last user of btrfs_bio::flags was removed in commit 326e1dbb5736
("block: remove management of bi_remaining when restoring original
bi_end_io"), remove it.

(Tagged for stable as the structure is heavily used and space savings
are desirable.)
