The patch titled Subject: fs: don't compile in drop_caches.c when CONFIG_SYSCTL=n has been removed from the -mm tree. Its filename was fs-dont-compile-in-drop_cachesc-when-config_sysctl=n.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Josh Triplett <josh@xxxxxxxxxxxxxxxx> Subject: fs: don't compile in drop_caches.c when CONFIG_SYSCTL=n drop_caches.c provides code only invokable via sysctl, so don't compile it in when CONFIG_SYSCTL=n.
