All\nthese conditions are pagecache and/or filesystem corruption.\n\nThe problem comes about because we didn\u0027t keep track of which buffers\nactually are new or old. However it is not enough just to keep only this\nstate, because at the point we start dirtying parts of the page (new\nblocks, with zeroes), the handling of IO errors becomes impossible without\nbuffers because the page may only be partially uptodate, in which case the\npage flags allone cannot capture the state of the parts of the page.\n\nSo allocate all buffers for the page upfront, but leave them unattached so\nthat they don\u0027t pick up any other references and can be freed when we\u0027re\ndone. If the error path is hit, then zero the new buffers as the regular\nbuffer path does, then attach the buffers to the page so that it can\nactually be written out correctly and be subject to the normal IO error\nhandling paths.\n\nAs an upshot, we save 1K of kernel stack on ia64 or powerpc 64K page\nsystems.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "68671f35fe8d785277118a333c88768a4f894917", "tree": "50cb5a378db1b021c2ec3573388af3480df49791", "parents": [ "ef8b4520bd9f8294ffce9abd6158085bde5dc902" ], "author": { "name": "Dmitry Monakhov", "email": "dmonakhov@openvz.org", "time": "Tue Oct 16 01:24:47 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Oct 16 09:42:53 2007 -0700" }, "message": "mm: add end_buffer_read helper function\n\nMove duplicated code from end_buffer_read_XXX methods to separate helper\nfunction.\n\nSigned-off-by: Dmitry Monakhov \u003cdmonakhov@openvz.org\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "557ed1fa2620dc119adb86b34c614e152a629a80", "tree": "d00b31a7f197583c2bd8fffa1fd135fbbb5d6abc", "parents": [ "aadb4bc4a1f9108c1d0fbd121827c936c2ed4217" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Tue Oct 16 01:24:40 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Oct 16 09:42:53 2007 -0700" }, "message": "remove ZERO_PAGE\n\nThe commit b5810039a54e5babf428e9a1e89fc1940fabff11 contains the note\n\n A last caveat: the ZERO_PAGE is now refcounted and managed with rmap\n (and thus mapcounted and count towards shared rss). These writes to\n the struct page could cause excessive cacheline bouncing on big\n systems. There are a number of ways this could be addressed if it is\n an issue.\n\nAnd indeed this cacheline bouncing has shown up on large SGI systems.\nThere was a situation where an Altix system was essentially livelocked\ntearing down ZERO_PAGE pagetables when an HPC app aborted during startup.\nThis situation can be avoided in userspace, but it does highlight the\npotential scalability problem with refcounting ZERO_PAGE, and corner\ncases where it can really hurt (we don\u0027t want the system to livelock!).\n\nThere are several broad ways to fix this problem:\n1. add back some special casing to avoid refcounting ZERO_PAGE\n2. per-node or per-cpu ZERO_PAGES\n3. remove the ZERO_PAGE completely\n\nI will argue for 3. The others should also fix the problem, but they\nresult in more complex code than does 3, with little or no real benefit\nthat I can see.\n\nWhy? Inserting a ZERO_PAGE for anonymous read faults appears to be a\nfalse optimisation: if an application is performance critical, it would\nnot be doing many read faults of new memory, or at least it could be\nexpected to write to that memory soon afterwards. If cache or memory use\nis critical, it should not be working with a significant number of\nZERO_PAGEs anyway (a more compact representation of zeroes should be\nused).\n\nAs a sanity check -- mesuring on my desktop system, there are never many\nmappings to the ZERO_PAGE (eg. 2 or 3), thus memory usage here should not\nincrease much without it.\n\nWhen running a make -j4 kernel compile on my dual core system, there are\nabout 1,000 mappings to the ZERO_PAGE created per second, but about 1,000\nZERO_PAGE COW faults per second (less than 1 ZERO_PAGE mapping per second\nis torn down without being COWed). So removing ZERO_PAGE will save 1,000\npage faults per second when running kbuild, while keeping it only saves\nless than 1 page clearing operation per second. 1 page clear is cheaper\nthan a thousand faults, presumably, so there isn\u0027t an obvious loss.\n\nNeither the logical argument nor these basic tests give a guarantee of no\nregressions. However, this is a reasonable opportunity to try to remove\nthe ZERO_PAGE from the pagefault path. If it is found to cause regressions,\nwe can reintroduce it and just avoid refcounting it.\n\nThe /dev/zero ZERO_PAGE usage and TLB tricks also get nuked. I don\u0027t see\nmuch use to them except on benchmarks. All other users of ZERO_PAGE are\nconverted just to use ZERO_PAGE(0) for simplicity. We can look at\nreplacing them all and maybe ripping out ZERO_PAGE completely when we are\nmore satisfied with this solution.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by:
