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?
