workload showed up a bug in the lockless pagecache patch. Basically it\nwould go into an \"infinite\" loop, although it would sometimes be able to break\nout of the loop! The reason is a missing compiler barrier in the \"increment\nreference count unless it was zero\" case of the lockless pagecache protocol in\nthe gang lookup functions.\n\nThis would cause the compiler to use a cached value of struct page pointer to\nretry the operation with, rather than reload it. So the page might have been\nremoved from pagecache and freed (refcount\u003d\u003d0) but the lookup would not correctly\nnotice the page is no longer in pagecache, and keep attempting to increment the\nrefcount and failing, until the page gets reallocated for something else. This\nisn\u0027t a data corruption because the condition will be detected if the page has\nbeen reallocated. However it can result in a lockup.\n\nLinus points out that ACCESS_ONCE is also required in that pointer load, even\nif it\u0027s absence is not causing a bug on our particular build. The most general\nway to solve this is just to put an rcu_dereference in radix_tree_deref_slot.\n\nAssembly of find_get_pages,\nbefore:\n.L220:\n movq (%rbx), %rax #* ivtmp.1162, tmp82\n movq (%rax), %rdi #, prephitmp.1149\n.L218:\n testb $1, %dil #, prephitmp.1149\n jne .L217 #,\n testq %rdi, %rdi # prephitmp.1149\n je .L203 #,\n cmpq $-1, %rdi #, prephitmp.1149\n je .L217 #,\n movl 8(%rdi), %esi # \u003cvariable\u003e._count.counter, c\n testl %esi, %esi # c\n je .L218 #,\n\nafter:\n.L212:\n movq (%rbx), %rax #* ivtmp.1109, tmp81\n movq (%rax), %rdi #, ret\n testb $1, %dil #, ret\n jne .L211 #,\n testq %rdi, %rdi # ret\n je .L197 #,\n cmpq $-1, %rdi #, ret\n je .L211 #,\n movl 8(%rdi), %esi # \u003cvariable\u003e._count.counter, c\n testl %esi, %esi # c\n je .L212 #,\n\n(notice the obvious infinite loop in the first example, if page-\u003ecount remains 0)\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nReviewed-by: Paul E.

Just before writing a metadata\nbuffer to the journal, jbd2 will optionally call a commit trigger associated\nwith the buffer. If the journal is aborted, an abort trigger will be\ncalled on any dirty buffers as they are dropped from pending\ntransactions.\n\nocfs2 will use this feature.\n\nInitially I tried to come up with a more generic trigger that could be\nused for non-buffer-related events like transaction completion. It\ndoesn\u0027t tie nicely, because the information a buffer trigger needs\n(specific to a journal_head) isn\u0027t the same as what a transaction\ntrigger needs (specific to a tranaction_t or perhaps journal_t). So I\nimplemented a buffer set, with the understanding that\njournal/transaction wide triggers should be implemented separately.\n\nThere is only one trigger set allowed per buffer. I can\u0027t think of any\nreason to attach more than one set.

Filesystems can now act on\nthis flag in their write_begin function. Change __grab_cache_page to\naccept a nofs argument as well, to honour that flag (while we\u0027re there,\nchange the name to grab_cache_page_write_begin which is more instructive\nand does away with random leading underscores).\n\nThis is really a more flexible way to go in the end anyway -- if a\nfilesystem happens to want any extra allocations aside from the pagecache\nones in ints write_begin function, it may now use GFP_KERNEL (rather than\nGFP_NOFS) for common case allocations (eg. ocfs2_alloc_write_ctxt, for a\nrandom example).\n\n[kosaki.motohiro@jp.fujitsu.com: fix ubifs]\n[kosaki.motohiro@jp.fujitsu.com: fix fuse]\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nReviewed-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: \u003cstable@kernel.org\u003e\t\t[2.6.28.x]\nSigned-off-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\n[ Cleaned up the calling convention: just pass in the AOP flags\n untouched to the grab_cache_page_write_begin() function.
