First, a task running on\nanother CPU may be updating its flags while the freezer attempts to set\nPF_FREEZE for it and this may leave the task\u0027s flags in an inconsistent\nstate. Second, there is a potential race between freeze_process() and\nrefrigerator() in which freeze_process() running on one CPU is reading a\ntask\u0027s PF_FREEZE flag while refrigerator() running on another CPU has just\nset PF_FROZEN for the same task and attempts to reset PF_FREEZE for it. If\nthe refrigerator wins the race, freeze_process() will state that PF_FREEZE\nhasn\u0027t been set for the task and will set it unnecessarily, so the task\nwill go to the refrigerator once again after it\u0027s been thawed.\n\nTo solve first of these problems we need to stop using PF_FREEZE to tell\ntasks that they should go to the refrigerator. Instead, we can introduce a\nspecial TIF_*** flag and use it for this purpose, since it is allowed to\nchange the other tasks\u0027 TIF_*** flags and there are special calls for it.\n\nTo avoid the freeze_process()-refrigerator() race we can make\nfreeze_process() to always check the task\u0027s PF_FROZEN flag after it\u0027s read\nits \"freeze\" flag.

Since only the softwall version might sleep,\nthis led to bugs with possible sleeping in interrupt context on more than\none occassion.\n\nThe hardwall version requires that the current tasks mems_allowed allows\nthe node of the specified zone (or that you\u0027re in interrupt or that\n__GFP_THISNODE is set or that you\u0027re on a one cpuset system.)\n\nThe softwall version, depending on the gfp_mask, might allow a node if it\nwas allowed in the nearest enclusing cpuset marked mem_exclusive (which\nrequires taking the cpuset lock \u0027callback_mutex\u0027 to evaluate.)\n\nThis patch removes the cpuset_zone_allowed() call, and forces the caller to\nexplicitly choose between the hardwall and the softwall case.\n\nIf the caller wants the gfp_mask to determine this choice, they should (1)\nbe sure they can sleep or that __GFP_HARDWALL is set, and (2) invoke the\ncpuset_zone_allowed_softwall() routine.\n\nThis adds another 100 or 200 bytes to the kernel text space, due to the few\nlines of nearly duplicate code at the top of both cpuset_zone_allowed_*\nroutines. It should save a few instructions executed for the calls that\nturned into calls of cpuset_zone_allowed_hardwall, thanks to not having to\nset (before the call) then check (within the call) the __GFP_HARDWALL flag.\n\nFor the most critical call, from get_page_from_freelist(), the same\ninstructions are executed as before -- the old cpuset_zone_allowed()\nroutine it used to call is the same code as the\ncpuset_zone_allowed_softwall() routine that it calls now.\n\nNot a perfect win, but seems worth it, to reduce this chance of hitting a\nsleeping with irq off complaint again.\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "5f8442edfb214908e9c6ca1142bf882c9bc364e5", "tree": "32c6e81d78cdedf03a01e418df05ff8a8f76c7bf", "parents": [ "d4c3cca941b64a938eaa9734585a93547c6be323" ], "author": { "name": "Eric W.

It simply counts the\nnumber of bytes passed into read() and write(). So if a process reads 1MB\nfrom an already-cached file, it is accused of having performed 1MB of I/O,\nwhich is wrong.\n\n(David Wright had some comments on the applicability of the present logical IO accounting:\n\n For billing purposes it is useless but for workload analysis it is very\n useful\n\n read_bytes/read_calls average read request size\n write_bytes/write_calls average write request size\n\n read_bytes/read_blocks ie logical/physical can indicate hit rate or thrashing\n write_bytes/write_blocks ie logical/physical guess since pdflush writes can\n be missed\n\n I often look for logical larger than physical to see filesystem cache\n problems. And the bytes/cpusec can help find applications that are\n dominating the cache and causing slow interactive response from page cache\n contention.\n\n I want to find the IO intensive applications and make sure they are doing\n efficient IO. Thus the acctcms(sysV) or csacms command would give the high\n IO commands).\n\nThis patchset adds new accounting which tries to be more accurate. We account\nfor three things:\n\nreads:\n\n attempt to count the number of bytes which this process really did cause\n to be fetched from the storage layer. Done at the submit_bio() level, so it\n is accurate for block-backed filesystems. I also attempt to wire up NFS and\n CIFS.\n\nwrites:\n\n attempt to count the number of bytes which this process caused to be sent\n to the storage layer. This is done at page-dirtying time.\n\n The big inaccuracy here is truncate. If a process writes 1MB to a file\n and then deletes the file, it will in fact perform no writeout. But it will\n have been accounted as having caused 1MB of write.\n\n So...\n\ncancelled_writes:\n\n account the number of bytes which this process caused to not happen, by\n truncating pagecache.\n\n We _could_ just subtract this from the process\u0027s `write\u0027 accounting. But\n that means that some processes would be reported to have done negative\n amounts of write IO, which is silly.\n\n So we just report the raw number and punt this decision up to userspace.\n\nNow, we _could_ account for writes at the physical I/O level. But\n\n- This would require that we track memory-dirtying tasks at the per-page\n level (would require a new pointer in struct page).\n\n- It would mean that IO statistics for a process are usually only available\n long after that process has exitted. Which means that we probably cannot\n communicate this info via taskstats.\n\nThis patch:\n\nWire up the kernel-private data structures and the accessor functions to\nmanipulate them.\n\nCc: Jay Lan \u003cjlan@sgi.com\u003e\nCc: Shailabh Nagar \u003cnagar@watson.ibm.com\u003e\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nCc: Chris Sturtivant \u003ccsturtiv@sgi.com\u003e\nCc: Tony Ernst \u003ctee@sgi.com\u003e\nCc: Guillaume Thouvenin \u003cguillaume.thouvenin@bull.net\u003e\nCc: David Wright \u003cdaw@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1f29bcd739972f71f2fd5d5d265daf3e1208fa5e", "tree": "96e20e4d0a077d813d8625d6919aba9bd0b5ed13", "parents": [ "98d7340c360993fdd703609ff7462051e03cc2fb" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Sun Dec 10 02:19:10 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Sun Dec 10 09:55:41 2006 -0800" }, "message": "[PATCH] sysctl: remove unused \"context\" param\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: \"David S.
