Subject: [PATCH 14/45] btrfs: use bio fields for op and flags
Date: Sun, 5 Jun 2016 14:31:54 -0500 [thread overview]
Message-ID: <1465155145-10812-15-git-send-email-mchristi@redhat.com> (raw)
In-Reply-To: <1465155145-10812-1-git-send-email-mchristi@redhat.com>
From: Mike Christie <mchristi@redhat.com>
The bio REQ_OP and bi_rw rq_flag_bits are now always setup, so there is
no need to pass around the rq_flag_bits bits too. btrfs users should
should access the bio insead.

v2:
1. Fix merge_bio issue where instead of removing rw/op argument
I passed it in again to the merge_bio related functions.

Subject: [PATCH 14/45] btrfs: use bio fields for op and flags
Date: Sun, 5 Jun 2016 14:31:54 -0500 [thread overview]
Message-ID: <1465155145-10812-15-git-send-email-mchristi@redhat.com> (raw)
In-Reply-To: <1465155145-10812-1-git-send-email-mchristi@redhat.com>
From: Mike Christie <mchristi@redhat.com>
The bio REQ_OP and bi_rw rq_flag_bits are now always setup, so there is
no need to pass around the rq_flag_bits bits too. btrfs users should
should access the bio insead.

v2:
1. Fix merge_bio issue where instead of removing rw/op argument
I passed it in again to the merge_bio related functions.

Subject: [Ocfs2-devel] [PATCH 14/45] btrfs: use bio fields for op and flags
Date: Sun, 5 Jun 2016 14:31:54 -0500 [thread overview]
Message-ID: <1465155145-10812-15-git-send-email-mchristi@redhat.com> (raw)
In-Reply-To: <1465155145-10812-1-git-send-email-mchristi@redhat.com>
From: Mike Christie <mchristi@redhat.com>
The bio REQ_OP and bi_rw rq_flag_bits are now always setup, so there is
no need to pass around the rq_flag_bits bits too. btrfs users should
should access the bio insead.
Signed-off-by: Mike Christie <mchristi@redhat.com>

v2:
1. Fix merge_bio issue where instead of removing rw/op argument
I passed it in again to the merge_bio related functions.
