Subject: [PATCH] block: copy NOMERGE flag from bio to request
Date: Mon, 25 Apr 2016 16:50:14 -0700 [thread overview]
Message-ID: <a0145c1154f503d43b7258e8c4892d5da316dfd9.1461626525.git.shli@fb.com> (raw)
bio might have NOMERGE flag set, for example blk_queue_split sets it.
When we initiate request, copy this flag too.
