It is presently at http://ozlabs.org/~akpm/mmotm/broken-out/debugging-keep-track-of-page-owners.patch. Today you sent a new version. My earlier email showed the difference between these two versions. AFACIT that difference was undescribed. I can see that the new version uses the stack-tracing infrastructure, but the change to pagetypeinfo_showmixedcount_print() is a mystery. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
