    Subject[PATCH 4.14 188/267] btrfs: Remove btrfs_bio::flags member
    Date
    From: Qu Wenruo <wqu@suse.com>

    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.)
