The system then hangs, occasionally\nsoftlockup oopsing. Apparently ibmtr.c:tok_interrupt() doesn\u0027t expect\nto be called before tok_open(), but tok_interrupt() gets called anyway\nwhen the card is ejected.

"message": "Fix a bad error case handling in read_cache_page_async()\n\nCommit 6fe6900e1e5b6fa9e5c59aa5061f244fe3f467e2 introduced a nasty bug\nin read_cache_page_async().\n\nIt added a \"mark_page_accessed(page)\" at the final return path in\nread_cache_page_async().

This patch removes the vmstat calls from the\nslab allocators and provides its own handling.\n\nThe advantage is also that we can use a different frequency for the updates.\nRefreshing vm stats is a pretty fast job so we can run this every second and\nstagger this by only one tick. This will lead to some overlap in large\nsystems. F.e a system running at 250 HZ with 1024 processors will have 4 vm\nupdates occurring at once.\n\nHowever, the vm stats update only accesses per node information. It is only\nnecessary to stagger the vm statistics updates per processor in each node. Vm\ncounter updates occurring on distant nodes will not cause cacheline\ncontention.\n\nWe could implement an alternate approach that runs the first processor on each\nnode at the second and then each of the other processor on a node on a\nsubsequent tick. That may be useful to keep a large amount of the second free\nof timer activity. Maybe the timer folks will have some feedback on this one?\n\n[jirislaby@gmail.com: add missing break]\nCc: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Jiri Slaby \u003cjirislaby@gmail.com\u003e\nCc: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "455c017ae3934797653549704c286e7bcc3a9397", "tree": "7b5b67916b064e3ce7868082e0915f37b437aeb8", "parents": [ "8bb7844286fb8c9fce6f65d8288aeb09d03a5e0d" ], "author": { "name": "Rafael J.

It also increases mmap_sem hold time\n because of cache misses.\n\nMost of these scalability problems come from the fact that futexes are in\none global namespace.

Time has come for linux\nto have better threading performance.\n\nThe goal is to permit new futex commands to avoid :\n - Taking the mmap_sem semaphore, conflicting with other subsystems.\n - Modifying a ref_count on mm or an inode, still conflicting with mm or fs.\n\nThis is possible because, for one process using PTHREAD_PROCESS_PRIVATE\nfutexes, we only need to distinguish futexes by their virtual address, no\nmatter the underlying mm storage is.\n\nIf glibc wants to exploit this new infrastructure, it should use new\n_PRIVATE futex subcommands for PTHREAD_PROCESS_PRIVATE futexes.

So it\nhangs forever if dwork doesn\u0027t do this, or cancel_rearming_delayed_work/\ncancel_delayed_work was already called. It uses flush_workqueue() in a\nloop, so it can\u0027t be used if workqueue was freezed, and it is potentially\nlive- lockable on busy system if delay is small.\n\nWith this patch cancel_rearming_delayed_work() doesn\u0027t make any assumptions\nabout dwork, it can re-arm itself via queue_delayed_work(), or\nqueue_work(), or do nothing.\n\nAs a \"side effect\", cancel_work_sync() was changed to handle re-arming works\nas well.\n\nDisadvantages:\n\n\t- this patch adds wmb() to insert_work().\n\n\t- slowdowns the fast path (when del_timer() succeeds on entry) of\n\t cancel_rearming_delayed_work(), because wait_on_work() is called\n\t unconditionally. In that case, compared to the old version, we are\n\t doing \"unneeded\" lock/unlock for each online CPU.\n\n\t On the other hand, this means we don\u0027t need to use cancel_work_sync()\n\t after cancel_rearming_delayed_work().\n\n\t- complicates the code (.text grows by 130 bytes).\n\n[akpm@linux-foundation.org: fix speling]\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: David Chinner \u003cdgc@sgi.com\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Gautham Shenoy \u003cego@in.ibm.com\u003e\nAcked-by: Jarek Poplawski \u003cjarkao2@o2.pl\u003e\nCc: Srivatsa Vaddagiri \u003cvatsa@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "7b0834c26fd796c79dfcc3939ed2b9122b75246f", "tree": "870eb42cd02b9012fd0ab06d7efb5e7596376bad", "parents": [ "10ab825bdef8df510f99c703a5a2d9b13a4e31a5" ], "author": { "name": "Gautham R Shenoy", "email": "ego@in.ibm.com", "time": "Wed May 09 02:34:41 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 09 12:30:53 2007 -0700" }, "message": "Remove kthread_bind() call from _cpu_down()\n\nWe are anyway kthread_stop()ping other per-cpu kernel threads after\nmove_task_off_dead_cpu(), so we can do it with the stop_machine_run thread\nas well.\n\nI just checked with Vatsa if there was any subtle reason why they\nhad put in the kthread_bind() in cpu.c.
