Subject: [PATCH 5/5] block_dev: make blkdev_dio_pool a non-rescuing bioset
Date: Fri, 10 Mar 2017 17:00:47 +1100 [thread overview]
Message-ID: <148912564767.4002.1734839418362310960.stgit@noble> (raw)
In-Reply-To: <148912539296.4002.219258660543808741.stgit@noble>
Allocations from blkdev_dio_pool are never made under
generic_make_request, so this bioset does not need a rescuer thread.
