From: Colin Ian King <redacted> 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? Signed-off-by: Colin Ian King <redacted>
