Originally it was called whenever rss or\ntotal_vm got raised. Then many of those callsites were replaced by a timer\ntick call from account_system_time. Now Frank van Maarseveen reports that to\nbe found inadequate. How about this? Works for Frank.\n\nReplace update_mem_hiwater, a poor combination of two unrelated ops, by macros\nupdate_hiwater_rss and update_hiwater_vm. Don\u0027t attempt to keep\nmm-\u003ehiwater_rss up to date at timer tick, nor every time we raise rss (usually\nby 1): those are hot paths. Do the opposite, update only when about to lower\nrss (usually by many), or just before final accounting in do_exit. Handle\nmm-\u003ehiwater_vm in the same way, though it\u0027s much less of an issue. Demand\nthat whoever collects these hiwater statistics do the work of taking the\nmaximum with rss or total_vm.\n\nAnd there has been no collector of these hiwater statistics in the tree. The\nnew convention needs an example, so match Frank\u0027s usage by adding a VmPeak\nline above VmSize to /proc/\u003cpid\u003e/status, and also a VmHWM line above VmRSS\n(High-Water-Mark or High-Water-Memory).\n\nThere was a particular anomaly during mremap move, that hiwater_vm might be\ncaptured too high. A fleeting such anomaly remains, but it\u0027s quickly\ncorrected now, whereas before it would stick.\n\nWhat locking? None: if the app is racy then these statistics will be racy,\nit\u0027s not worth any overhead to make them exact. But whenever it suits,\nhiwater_vm is updated under exclusive mmap_sem, and hiwater_rss under\npage_table_lock (for now) or with preemption disabled (later on): without\ngoing to any trouble, minimize the time between reading current values and\nupdating, to minimize those occasions when a racing thread bumps a count up\nand back down in between.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "4a805e863d6b9466baf7084e1d6fdbe6e0628d8e", "tree": "531d26f7f339f316da8d932538e4dcf9c580461d", "parents": [ "1619cca2921f6927f4240e03f413d4165c7002fc" ], "author": { "name": "David S.
