From: <hidden>
Date: 2016-06-05 19:33:14
Also in:
dm-devel, linux-bcache, linux-block, linux-btrfs, linux-f2fs-devel, linux-fsdevel, linux-raid, linux-scsi, linux-xfs, lkml, ocfs2-devel
Subsystem:
filesystems (vfs and infrastructure), hfsplus filesystem, the rest · Maintainers:
Alexander Viro, Christian Brauner, Viacheslav Dubeyko, John Paul Adrian Glaubitz, Yangtao Li, Linus Torvalds
From: Mike Christie <redacted> Separate the op from the rq_flag_bits and have gfs2 set/get the bio using bio_set_op_attrs/bio_op.
