One are\nthe context dependent ones (can we sleep? can we enter filesystem? block\nsubsystem? should we use some extra reserves, etc.). The other ones are\nthe type of memory required and depend on how the algorithm is implemented\nrather than the point at which the memory is allocated (highmem? dma\nmemory? etc).\n\nSome of the functions which allocate a page and add it to page cache take\na gfp_t, but sometimes those functions or their callers aren\u0027t really\ndoing the right thing: when allocating pagecache page, the memory type\nshould be mapping_gfp_mask(mapping). When allocating radix tree nodes,\nthe memory type should be kernel mapped (not highmem) memory. The gfp_t\nargument should only really be needed for context dependent options.\n\nThis patch doesn\u0027t really solve that tangle in a nice way, but it does\nattempt to fix a couple of bugs.\n\n- find_or_create_page changes its radix-tree allocation to only include\n the main context dependent flags in order so the pagecache page may be\n allocated from arbitrary types of memory without affecting the\n radix-tree. In practice, slab allocations don\u0027t come from highmem\n anyway, and radix-tree only uses slab allocations. So there isn\u0027t a\n practical change (unless some fs uses GFP_DMA for pages).\n\n- grab_cache_page_nowait() is changed to allocate radix-tree nodes with\n GFP_NOFS, because it is not supposed to reenter the filesystem. This\n bug could cause lock recursion if a filesystem is not expecting the\n function to reenter the fs (as-per documentation).\n\nFilesystems should be careful about exactly what semantics they want and\nwhat they get when fiddling with gfp_t masks to allocate pagecache.

If the process has been OOM killed, the TIF_MEMDIE is set and it\nreturn immediately. This patch includes:\n\n1. add the case that the SIGKILL is sent by user processes. The\n process can try to get_user_pages() unlimited memory even if a user\n process has sent a SIGKILL to it(maybe a monitor find the process\n exceed its memory limit and try to kill it). In the old\n implementation, the SIGKILL won\u0027t be handled until the get_user_pages()\n returns.\n\n2. change the return value to be ERESTARTSYS. It makes no sense to\n return ENOMEM if the get_user_pages returned by getting a SIGKILL\n signal. Considering the general convention for a system call\n interrupted by a signal is ERESTARTNOSYS, so the current return value\n is consistant to that.\n\nLee:\n\nAn unfortunate side effect of \"make-get_user_pages-interruptible\" is that\nit prevents a SIGKILL\u0027d task from munlock-ing pages that it had mlocked,\nresulting in freeing of mlocked pages. Freeing of mlocked pages, in\nitself, is not so bad.

If the task that mlocked the\npages exits via SIGKILL, these pages would be left mlocked and\nunevictable.\n\nProposed fix:\n\nAdd another GUP flag to ignore sigkill when calling get_user_pages from\nmunlock()--similar to Kosaki Motohiro\u0027s \u0027IGNORE_VMA_PERMISSIONS flag for\nthe same purpose. We are not actually allocating memory in this case,\nwhich \"make-get_user_pages-interruptible\" intends to avoid. We\u0027re just\nmunlocking pages that are already resident and mapped, and we\u0027re reusing\nget_user_pages() to access those pages.\n\n??

Say \"Bad page map\" in print_bad_pte(), and add a TAINT_BAD_PAGE\nthere too.\n\nprint_bad_pte() show current-\u003ecomm unconditionally (though it should get\nrepeated in the usually irrelevant stack trace): sorry, I misled Nick\nPiggin to make it conditional on vm_mm \u003d\u003d current-\u003emm, but current-\u003emm is\nalready NULL in the exit case. Usually current-\u003ecomm is good, though\nexceptionally it may not be that of the mm (when \"swapoff\" for example).\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "8cc3b39221b0ecbd83a338948a8396df097fc656", "tree": "8a8617590f6bc9842c28a0fc4e5e5fbc93e95780", "parents": [ "79f4b7bf393e67bbffec807cc68caaefc72b82ee" ], "author": { "name": "Hugh Dickins", "email": "hugh@veritas.com", "time": "Tue Jan 06 14:40:06 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jan 06 15:59:07 2009 -0800" }, "message": "badpage: keep any bad page out of circulation\n\nUntil now the bad_page() checkers have special-cased PageReserved, keeping\nthose pages out of circulation thereafter.

The changelog for that patch was:\n:\n: The shrink_zone() logic can, under some circumstances, cause far too many\n: pages to be reclaimed. Say, we\u0027re scanning at high priority and suddenly\n: hit a large number of reclaimable pages on the LRU.\n:\n: Change things so we bale out when SWAP_CLUSTER_MAX pages have been\n: reclaimed.\n:\n: Problem is, this change caused significant imbalance in inter-zone scan\n: balancing by truncating scans of larger zones.\n:\n: Suppose, for example, ZONE_HIGHMEM is 10x the size of ZONE_NORMAL. The zone\n: balancing algorithm would require that if we\u0027re scanning 100 pages of\n: ZONE_HIGHMEM, we should scan 10 pages of ZONE_NORMAL. But this logic will\n: cause the scanning of ZONE_HIGHMEM to bale out after only 32 pages are\n: reclaimed. Thus effectively causing smaller zones to be scanned relatively\n: harder than large ones.\n:\n: Now I need to remember what the workload was which caused me to write this\n: patch originally, then fix it up in a different way...\n\nAnd we haven\u0027t demonstrated that whatever problem caused that reversion is\nnot being reintroduced by this change in 2008.\n\nSigned-off-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" } ], "next": "ebdd4aea8d736e3b5ce27ab0a26860c9fded341b" }
