      "message": "[PATCH] mm: split page table lock\n\nChristoph Lameter demonstrated very poor scalability on the SGI 512-way, with\na many-threaded application which concurrently initializes different parts of\na large anonymous area.\n\nThis patch corrects that, by using a separate spinlock per page table page, to\nguard the page table entries in that page, instead of using the mm\u0027s single\npage_table_lock.  (But even then, page_table_lock is still used to guard page\ntable allocation, and anon_vma allocation.)\n\nIn this implementation, the spinlock is tucked inside the struct page of the\npage table page: with a BUILD_BUG_ON in case it overflows - which it would in\nthe case of 32-bit PA-RISC with spinlock debugging enabled.\n\nSplitting the lock is not quite for free: another cacheline access.  Ideally,\nI suppose we would use split ptlock only for multi-threaded processes on\nmulti-cpu machines; but deciding that dynamically would have its own costs.\nSo for now enable it by config, at some number of cpus - since the Kconfig\nlanguage doesn\u0027t support inequalities, let preprocessor compare that with\nNR_CPUS.  But I don\u0027t think it\u0027s worth being user-configurable: for good\ntesting of both split and unsplit configs, split now at 4 cpus, and perhaps\nchange that to 8 later.\n\nThere is a benefit even for singly threaded processes: kswapd can be attacking\none part of the mm while another part is busy faulting.\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"

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"
