Subject: [PATCH 07/14] block: make QUEUE_SYSFS_BIT_FNS a little more useful
Date: Sun, 26 Jul 2020 17:03:26 +0200	[thread overview]
Message-ID: <20200726150333.305527-8-hch@lst.de> (raw)
In-Reply-To: <20200726150333.305527-1-hch-jcswGhMUV9g@public.gmane.org>

Generate the queue_sysfs_entry given that we have all the required
information for it, and rename the generated show and store methods
to match the other ones in the file.
