Subject: [PATCH 07/35] btrfs: have submit_one_bio users setup bio bi_op
Date: Tue, 5 Jan 2016 14:53:10 -0600 [thread overview]
Message-ID: <1452027218-32303-8-git-send-email-mchristi@redhat.com> (raw)
In-Reply-To: <1452027218-32303-1-git-send-email-mchristi@redhat.com>
From: Mike Christie <mchristi@redhat.com>
This patch has btrfs's submit_one_bio callers set
the bio->bi_op to a REQ_OP and the bi_rw to rq_flag_bits.
The next patches will continue to convert btrfs,
so submit_bio_hook and merge_bio_hook
related code will be modified to take only the bio. I did
not do it in this patch to try and keep it smaller.
Note:
I have run xfs tests on these btrfs patches. There were some failures
with and without the patches. I have not had time to track down why
xfstest fails without the patches.

Subject: [Ocfs2-devel] [PATCH 07/35] btrfs: have submit_one_bio users setup bio bi_op
Date: Tue, 5 Jan 2016 14:53:10 -0600 [thread overview]
Message-ID: <1452027218-32303-8-git-send-email-mchristi@redhat.com> (raw)
In-Reply-To: <1452027218-32303-1-git-send-email-mchristi@redhat.com>
From: Mike Christie <mchristi@redhat.com>
This patch has btrfs's submit_one_bio callers set
the bio->bi_op to a REQ_OP and the bi_rw to rq_flag_bits.
The next patches will continue to convert btrfs,
so submit_bio_hook and merge_bio_hook
related code will be modified to take only the bio. I did
not do it in this patch to try and keep it smaller.
Note:
I have run xfs tests on these btrfs patches. There were some failures
with and without the patches. I have not had time to track down why
xfstest fails without the patches.
