And I don't want to Move recent_rotated and recent_scanned prints next to file lru lists just because the pageout code in vmscan.c keeps track of how many of the mem/swap backed and file backed pages are referenced, and the higher the rotated/scanned ratio, the more valuable that cache is. Move five lru lists and associated debug informations together can make things convenience. :-) Regards, Wanpeng Li >turn on debugging and then look for the extra information hiding in >the middle of regular stats. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
