Subject: [PATCH 09/45] block discard: use bio set op accessor
Date: Sun, 5 Jun 2016 14:31:49 -0500 [thread overview]
Message-ID: <1465155145-10812-10-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>
This converts the block issue discard helper and users to use
the bio_set_op_attrs accessor and only pass in the operation flags
like REQ_SEQURE.
Signed-off-by: Mike Christie <mchristi@redhat.com>
