A previous commit fixed this by adding a check to the sync\nnotifier to not wake up the sync thread of CPU A if it\u0027s the current task.\n\nBut this is still not sufficient to prevent deadlocks.\n\nSync thread of CPU A could be the current task on CPU B and sync thread of\nCPU B could be the current task on CPU A. At this point, if sync notifier\nof CPU A and B try to wake up the sync threads of CPU A and B, it will\nresult in CPU A waiting for the current task in CPU B to get switched out\nand CPU B waiting for the current task in CPU A to get switched out. This\nwill result in a deadlock.\n\nPrevent this scenario from happening by pinning the sync threads of each\nCPU to run on that CPU.

At the time the\nOOM killer was triggered there was 4GB out of 36GB free in zone 1. The\nproblem was that alloc_fdtable was allocating an order 3 page (32KiB) to\nhold a bitmap, and there was sufficient fragmentation that the largest\npage available was 8KiB.\n\nI find the logic that PAGE_ALLOC_COSTLY_ORDER can\u0027t fail pretty dubious\nbut I do agree that order 3 allocations are very likely to succeed.\n\nThere are always pathologies where order \u003e 0 allocations can fail when\nthere are copious amounts of free memory available. Using the pigeon\nhole principle it is easy to show that it requires 1 page more than 50%\nof the pages being free to guarantee an order 1 (8KiB) allocation will\nsucceed, 1 page more than 75% of the pages being free to guarantee an\norder 2 (16KiB) allocation will succeed and 1 page more than 87.5% of\nthe pages being free to guarantee an order 3 allocate will succeed.\n\nA server churning memory with a lot of small requests and replies like\nmemcached is a common case that if anything can will skew the odds\nagainst large pages being available.\n\nTherefore let\u0027s not give external applications a practical way to kill\nlinux server applications, and specify __GFP_NORETRY to the kmalloc in\nalloc_fdmem. Unless I am misreading the code and by the time the code\nreaches should_alloc_retry in __alloc_pages_slowpath (where\n__GFP_NORETRY becomes signification). We have already tried everything\nreasonable to allocate a page and the only thing left to do is wait. So\nnot waiting and falling back to vmalloc immediately seems like the\nreasonable thing to do even if there wasn\u0027t a chance of triggering the\nOOM killer.\n\nSigned-off-by: \"Eric W.

These appear as abrupt\nchanges in the values reported by the hardware from very low values to\nvery high values, which can cause unexpected vertical jumps in the\nposition of the mouse pointer.\n\nWhat seems to be happening is that the value is wrapping to a two\u0027s\ncompliment negative value of higher resolution than the 13-bit value\nreported by the hardware, with the high-order bits being truncated. This\npatch adds handling for these values by converting them to the\nappropriate negative values.\n\nThe only tricky part about this is deciding when to treat a number as\nnegative. It stands to reason that if out of range values can be\nreported on the low end then it could also happen on the high end, so\nnot all out of range values should be treated as negative. The approach\ntaken here is to split the difference between the maximum legitimate\nvalue for the axis and the maximum possible value that the hardware can\nreport, treating values greater than this number as negative and all\nother values as positive. This can be tweaked later if hardware is found\nthat operates outside of these parameters.\n\nBugLink: http://bugs.launchpad.net/bugs/1001251\nSigned-off-by: Seth Forshee \u003cseth.forshee@canonical.com\u003e\nReviewed-by: Daniel Kurtz \u003cdjkurtz@chromium.org\u003e\nSigned-off-by: Dmitry Torokhov \u003cdmitry.torokhov@gmail.com\u003e\n[bwh: Backported to 3.2: adjust context]\nSigned-off-by: Ben Hutchings \u003cben@decadent.org.uk\u003e\nCc: Li Zefan \u003clizefan@huawei.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n" }, { "commit": "b249f99c023402a192e1af812326c5092e64175f", "tree": "49b94c6486350105fe8334c9e81b105dc557f6af", "parents": [ "ec90b6113735a9f9fcb64a604b28f446fe03ded2" ], "author": { "name": "Bojan Smojver", "email": "bojan@rexursive.com", "time": "Sun Apr 29 22:42:06 2012 +0200" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Thu Feb 20 10:45:33 2014 -0800" }, "message": "PM / Hibernate: Hibernate/thaw fixes/improvements\n\ncommit 5a21d489fd9541a4a66b9a500659abaca1b19a51 upstream.\n\n 1.

Luckily, there\u0027s no\ncallback that doesn\u0027t use the helper functions that requires this. But\nthere soon will be and this needs to be fixed.\n\nUse a set_function_trace_op to store the ftrace_op to set the\nfunction_trace_op to when it is safe to do so (during the update function\nwithin the breakpoint or stop machine calls).
