Subject: [PATCH] block/mq-deadline: Move dd_queued() to fix defined but not used warning
Date: Mon, 30 Aug 2021 11:11:28 +0200	[thread overview]
Message-ID: <20210830091128.1854266-1-geert@linux-m68k.org> (raw)

If CONFIG_BLK_DEBUG_FS=n:

    block/mq-deadline.c:274:12: warning: ‘dd_queued’ defined but not used [-Wunused-function]
      274 | static u32 dd_queued(struct deadline_data *dd, enum dd_prio prio)
	  |            ^~~~~~~~~

Fix this by moving dd_queued() just before the sole function that calls
it.

Fixes: 7b05bf771084ff78 ("Revert "block/mq-deadline: Prioritize high-priority requests"")
Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
