I have 16Gb of highmem (pretty much all ununsed) so presumably that'd fill the highmem first (pagecache?) > Is it reproducible? Will try again. Presumably "find /" should do it? ;-) M. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org. For more info on Linux MM, see: http://www.linux-mm.org/
