[PATCH] add OOM debug
This patch provides more debug info when the system is OOM. It displays memory stats (basically sysrq-m info) from __alloc_pages() when page allocation fails and during OOM kill. Thanks to Dave Jones for coming up with the idea. Signed-off-by: Janet Morgan <janetmor@us.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
