From: Colin Ian King Date: Tue, 10 Apr 2018 23:29:55 +0000 (-0700) Subject: mm/swapfile.c: make pointer swap_avail_heads static X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=bfc6b1cabce28d46d2559855ca224992e14fede7;p=openwrt%2Fstaging%2Fblogic.git mm/swapfile.c: make pointer swap_avail_heads static The pointer swap_avail_heads is local to the source and does not need to be in global scope, so make it static. Cleans up sparse warning: mm/swapfile.c:88:19: warning: symbol 'swap_avail_heads' was not declared. Should it be static?
