Subject: [PATCH 13/14] mm/page_alloc: Move prototype for find_suitable_fallback
Date: Thu, 20 May 2021 09:48:08 +0100 [thread overview]
Message-ID: <20210520084809.8576-14-mgorman@techsingularity.net> (raw)
In-Reply-To: <20210520084809.8576-1-mgorman@techsingularity.net>
make W=1 generates the following warning in mmap_lock.c for allnoconfig
mm/page_alloc.c:2670:5: warning: no previous prototype for ‘find_suitable_fallback’ [-Wmissing-prototypes]
int find_suitable_fallback(struct free_area *area, unsigned int order,
^~~~~~~~~~~~~~~~~~~~~~
find_suitable_fallback is only shared outside of page_alloc.c for
CONFIG_COMPACTION but to suppress the warning, move the protype
outside of CONFIG_COMPACTION. It is not worth the effort at
this time to find a clever way of allowing compaction.c to share
the code or avoid the use entirely as the function is called
on relatively slow paths.
