      "message": "[PATCH] fix for __generic_file_aio_read() to return 0 on EOF\n\nI came across the following problem while running ltp-aiodio testcases from\nltp-full-20050405 on linux-2.6.12-rc3-mm3.  I tried running the tests with\nEXT3 as well as JFS filesystems.\n\nOne or two fsx-linux testcases were hung after some time.  These testcases\nwere hanging at wait_for_all_aios().\n\nDebugging shows that there were some iocbs which were not getting completed\neventhough the last retry for those returned -EIOCBQUEUED.  Also all such\npending iocbs represented READ operation.\n\nFurther debugging revealed that all such iocbs hit EOF in the DIO layer.\nTo be more precise, the \"pos\" from which they were trying to read was\ngreater than the \"size\" of the file.  So the generic_file_direct_IO\nreturned 0.\n\nThis happens rarely as there is already a check in\n__generic_file_aio_read(), for whether \"pos\" \u003c \"size\" before calling direct\nIO routine.\n\n\u003esize \u003d i_size_read(inode);\n\u003eif (pos \u003c size) {\n\u003e\t  retval \u003d generic_file_direct_IO(READ, iocb,\n\u003e                               iov, pos, nr_segs);\n\nBut for READ, we are taking the inode-\u003ei_sem only in the DIO layer.  So it\nis possible that some other process can change the size of the file before\nwe take the i_sem.  In such a case ( when \"pos\" \u003e \"size\"), the\n__generic_file_aio_read() would return -EIOCBQUEUED even though there were\nno I/O requests submitted by the DIO layer.  This would cause the AIO layer\nto expect aio_complete() for THE iocb, which doesnot happen.  And thus the\ntest hangs forever, waiting for an I/O completion, where there are no\nrequests submitted at all.\n\nThe following patch makes __generic_file_aio_read() return 0 (instead of\nreturning -EIOCBQUEUED), on getting 0 from generic_file_direct_IO(), so\nthat the AIO layer does the aio_complete().\n\nTesting:\n\nI have tested the patch on a SMP machine(with 2 Pentium 4 (HT)) running\nlinux-2.6.12-rc3-mm3.  I ran the ltp-aiodio testcases and none of the\nfsx-linux tests hung.  Also the aio-stress tests ran without any problem.\n\nSigned-off-by: Suzuki K P \u003csuzuki@in.ibm.com\u003e\nSigned-off-by: Suparna Bhattacharya \u003csuparna@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] DocBook: changes and extensions to the kernel documentation\n\nI have recompiled Linux kernel 2.6.11.5 documentation for me and our\nuniversity students again.  The documentation could be extended for more\nsources which are equipped by structured comments for recent 2.6 kernels.  I\nhave tried to proceed with that task.  I have done that more times from 2.6.0\ntime and it gets boring to do same changes again and again.  Linux kernel\ncompiles after changes for i386 and ARM targets.  I have added references to\nsome more files into kernel-api book, I have added some section names as well.\n So please, check that changes do not break something and that categories are\nnot too much skewed.\n\nI have changed kernel-doc to accept \"fastcall\" and \"asmlinkage\" words reserved\nby kernel convention.  Most of the other changes are modifications in the\ncomments to make kernel-doc happy, accept some parameters description and do\nnot bail out on errors.  Changed \u003cpid\u003e to @pid in the description, moved some\n#ifdef before comments to correct function to comments bindings, etc.\n\nYou can see result of the modified documentation build at\n  http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz\n\nSome more sources are ready to be included into kernel-doc generated\ndocumentation.  Sources has been added into kernel-api for now.  Some more\nsection names added and probably some more chaos introduced as result of quick\ncleanup work.\n\nSigned-off-by: Pavel Pisa \u003cpisa@cmp.felk.cvut.cz\u003e\nSigned-off-by: Martin Waitz \u003ctali@admingilde.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

Looks too clever for its own good :) It\nshouldn\u0027t really know so much about page reclaim internals.\n\n- don\u0027t guess about what effective page reclaim might involve.\n\n- don\u0027t randomly flush out all dirty data if some unlikely thing\n  happens (alloc returns NULL). page reclaim can (sort of :P) handle\n  it.\n\nI think the main motivation is trying to avoid pool-\u003elock at all costs.\nHowever the first allocation is attempted with __GFP_WAIT cleared, so it\nwill be \u0027can_try_harder\u0027 if it hits the page allocator.  So if allocation\nstill fails, then we can probably afford to hit the pool-\u003elock - and what\u0027s\nthe alternative?  Try page reclaim and hit zone-\u003elru_lock?\n\nA nice upshot is that we don\u0027t need to do any fancy memory barriers or do\n(intentionally) racy access to pool-\u003e fields outside the lock.\n\nSigned-off-by: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] freepgt: free_pgtables use vma list\n\nRecent woes with some arches needing their own pgd_addr_end macro; and 4-level\nclear_page_range regression since 2.6.10\u0027s clear_page_tables; and its\nlong-standing well-known inefficiency in searching throughout the higher-level\npage tables for those few entries to clear and free: all can be blamed on\nignoring the list of vmas when we free page tables.\n\nReplace exit_mmap\u0027s clear_page_range of the total user address space by\nfree_pgtables operating on the mm\u0027s vma list; unmap_region use it in the same\nway, giving floor and ceiling beyond which it may not free tables.  This\nbrings lmbench fork/exec/sh numbers back to 2.6.10 (unless preempt is enabled,\nin which case latency fixes spoil unmap_vmas throughput).\n\nBeware: the do_mmap_pgoff driver failure case must now use unmap_region\ninstead of zap_page_range, since a page table might have been allocated, and\ncan only be freed while it is touched by some vma.\n\nMove free_pgtables from mmap.c to memory.c, where its lower levels are adapted\nfrom the clear_page_range levels.  (Most of free_pgtables\u0027 old code was\nactually for a non-existent case, prev not properly set up, dating from before\nhch gave us split_vma.) Pass mmu_gather** in the public interfaces, since we\nmight want to add latency lockdrops later; but no attempt to do so yet, going\nby vma should itself reduce latency.\n\nBut what if is_hugepage_only_range?  Those ia64 and ppc64 cases need careful\nexamination: put that off until a later patch of the series.\n\nWhat of x86_64\u0027s 32bit vdso page __map_syscall32 maps outside any vma?\n\nAnd the range to sparc64\u0027s flush_tlb_pgtables?  It\u0027s less clear to me now that\nwe need to do more than is done here - every PMD_SIZE ever occupied will be\nflushed, do we really have to flush every PGDIR_SIZE ever partially occupied? \nA shame to complicate it unnecessarily.\n\nSpecial thanks to David Miller for time spent repairing my ceilings.\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"
