The patch titled vmscan: don't export nr_saved_scan in /proc/zoneinfo has been removed from the -mm tree. Its filename was vmscan-dont-export-nr_saved_scan-in-proc-zoneinfo.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: vmscan: don't export nr_saved_scan in /proc/zoneinfo From: Wu Fengguang <fengguang.wu@xxxxxxxxx> The lru->nr_saved_scan's are not meaningful counters for even kernel developers. They typically are smaller than 32 and are always 0 for large lists. So remove them from /proc/zoneinfo. Hopefully this interface change won't break too many scripts. /proc/zoneinfo is too unstructured to be script friendly, and I wonder the affected scripts - if there are any - are still bleeding since the not long ago commit "vmscan: split LRU lists into anon & file sets", which also touched the "scanned" line :) If we are to re-export accumulated vmscan counts in the future, they can go to new lines in /proc/zoneinfo instead of the current form, or to /sys/devices/system/node/node0/meminfo?
