Even if CONFIG_DEBUG_VM=n gcc genereates code for some VM_BUG_ON() for example VM_BUG_ON(!PageCompound(page) || !PageHead(page)); in do_huge_pmd_wp_page() generates 114 bytes of code. But they mostly disappears when I split this VM_BUG_ON into two: -VM_BUG_ON(!PageCompound(page) || !PageHead(page)); +VM_BUG_ON(!PageCompound(page)); +VM_BUG_ON(!PageHead(page)); weird... but anyway after this patch code disappears completely. add/remove: 0/0 grow/shrink: 7/97 up/down: 135/-1784 (-1649) Signed-off-by: Konstantin Khlebnikov <khlebnikov@openvz.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: "H.
