Subject: [PATCH 22/32] block/fs/drivers: set bi_op to REQ_OP
Date: Wed,  4 Nov 2015 16:08:19 -0600	[thread overview]
Message-ID: <1446674909-5371-23-git-send-email-mchristi@redhat.com> (raw)
In-Reply-To: <1446674909-5371-1-git-send-email-mchristi@redhat.com>

From: Mike Christie <mchristi@redhat.com>

This patch sets the bi_op to a REQ_OP for users where it
was a simple one line change.

For compat reasons, we are still ORing the op into bi_rw. This
will be dropped in later patches in this series when everyone
is updated.
