Subject: [PATCH 1/2] block: remove commented out code from diskstats_show
Date: Thu, 20 Jan 2022 11:52:47 +0100 [thread overview]
Message-ID: <20220120105248.117025-2-dwagner@suse.de> (raw)
In-Reply-To: <20220120105248.117025-1-dwagner@suse.de>
The diskstats format is ABI, so we just can't add a new header. The
code snippet has been commented out since at least v2.6.12-rc2.
Remove it.
