If the offset reaches the last mapped\naddress of the mm then it then it starts over at the first\naddress.\n\nThe per-task nature of the working set sampling functionality in this tree\nallows such constant rate, per task, execution-weight proportional sampling\nof the working set, with an adaptive sampling interval/frequency that\ngoes from once per 100ms up to just once per 8 seconds. The current\nsampling volume is 256 MB per interval.\n\nAs tasks mature and converge their working set, so does the\nsampling rate slow down to just a trickle, 256 MB per 8\nseconds of CPU time executed.\n\nThis, beyond being adaptive, also rate-limits rarely\nexecuting systems and does not over-sample on overloaded\nsystems.\n\n[ In AutoNUMA speak, this patch deals with the effective sampling\n rate of the \u0027hinting page fault\u0027. AutoNUMA\u0027s scanning is\n currently rate-limited, but it is also fundamentally\n single-threaded, executing in the knuma_scand kernel thread,\n so the limit in AutoNUMA is global and does not scale up with\n the number of CPUs, nor does it scan tasks in an execution\n proportional manner.\n\n So the idea of rate-limiting the scanning was first implemented\n in the AutoNUMA tree via a global rate limit. This patch goes\n beyond that by implementing an execution rate proportional\n working set sampling rate that is not implemented via a single\n global scanning daemon. ]\n\n[ Dan Carpenter pointed out a possible NULL pointer dereference in the\n first version of this patch. ]\n\nBased-on-idea-by: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nBug-Found-By: Dan Carpenter \u003cdan.carpenter@oracle.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\n[ Wrote changelog and fixed bug. ]\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\nSigned-off-by: Mel Gorman \u003cmgorman@suse.de\u003e\nReviewed-by: Rik van Riel \u003criel@redhat.com\u003e\n" }, { "commit": "cbee9f88ec1b8dd6b58f25f54e4f52c82ed77690", "tree": "d4cfbcfa3e89742216cd792d4aa914356406b532", "parents": [ "a720094ded8cbb303111035be91858011d2eac71" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Thu Oct 25 14:16:43 2012 +0200" }, "committer": { "name": "Mel Gorman", "email": "mgorman@suse.de", "time": "Tue Dec 11 14:42:45 2012 +0000" }, "message": "mm: numa: Add fault driven placement and migration\n\nNOTE: This patch is based on \"sched, numa, mm: Add fault driven\n\tplacement and migration policy\" but as it throws away all the policy\n\tto just leave a basic foundation I had to drop the signed-offs-by.\n\nThis patch creates a bare-bones method for setting PTEs pte_numa in the\ncontext of the scheduler that when faulted later will be faulted onto the\nnode the CPU is running on.

So, I just mimic the alloc_page_vma() node computation\nlogic--sort of.\n\nNote: we could use this function to implement a MPOL_MF_STRICT\nbehavior when migrating pages to match mbind() mempolicy--e.g.,\nto ensure that pages in an interleaved range are reinterleaved\nrather than left where they are when they reside on any page in\nthe interleave nodemask.\n\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nReviewed-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n[ Added MPOL_F_LAZY to trigger migrate-on-fault;\n simplified code now that we don\u0027t have to bother\n with special crap for interleaved ]\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\nSigned-off-by: Mel Gorman \u003cmgorman@suse.de\u003e\n" }, { "commit": "d3a710337b0590f43fd236d5e6518439afc7410a", "tree": "19a03d787d1795c8212fc2c9ede5397ba0a32c85", "parents": [ "479e2802d09f1e18a97262c4c6f8f17ae5884bd8" ], "author": { "name": "Lee Schermerhorn", "email": "lee.schermerhorn@hp.com", "time": "Thu Oct 25 14:16:29 2012 +0200" }, "committer": { "name": "Mel Gorman", "email": "mgorman@suse.de", "time": "Tue Dec 11 14:42:40 2012 +0000" }, "message": "mm: mempolicy: Add MPOL_NOOP\n\nThis patch augments the MPOL_MF_LAZY feature by adding a \"NOOP\" policy\nto mbind().

(By the way, the test program\n: tools/testing/selftests/epoll/test_epoll.c does not compile...)\n:\n: There are one or two places where the behavior seems a little strange,\n: so I have a question or two at the end of this mail. But other than\n: that, I want to check my understanding so that the interface can be\n: correctly documented.\n:\n: Just to go though my understanding, the problem is the following\n: scenario in a multithreaded application:\n:\n: 1. Multiple threads are performing epoll_wait() operations,\n: and maintaining a user-space cache that contains information\n: corresponding to each file descriptor being monitored by\n: epoll_wait().\n:\n: 2. At some point, a thread wants to delete (EPOLL_CTL_DEL)\n: a file descriptor from the epoll interest list, and\n: delete the corresponding record from the user-space cache.\n:\n: 3. The problem with (2) is that some other thread may have\n: previously done an epoll_wait() that retrieved information\n: about the fd in question, and may be in the middle of using\n: information in the cache that relates to that fd. Thus,\n: there is a potential race.\n:\n: 4. The race can\u0027t solved purely in user space, because doing\n: so would require applying a mutex across the epoll_wait()\n: call, which would of course blow thread concurrency.\n:\n: Right?\n:\n: Your solution is the EPOLL_CTL_DISABLE operation. I want to\n: confirm my understanding about how to use this flag, since\n: the description that has accompanied the patches so far\n: has been a bit sparse\n:\n: 0. In the scenario you\u0027re concerned about, deleting a file\n: descriptor means (safely) doing the following:\n: (a) Deleting the file descriptor from the epoll interest list\n: using EPOLL_CTL_DEL\n: (b) Deleting the corresponding record in the user-space cache\n:\n: 1. It\u0027s only meaningful to use this EPOLL_CTL_DISABLE in\n: conjunction with EPOLLONESHOT.\n:\n: 2. Using EPOLL_CTL_DISABLE without using EPOLLONESHOT in\n: conjunction is a logical error.\n:\n: 3. The correct way to code multithreaded applications using\n: EPOLL_CTL_DISABLE and EPOLLONESHOT is as follows:\n:\n: a. All EPOLL_CTL_ADD and EPOLL_CTL_MOD operations should\n: should EPOLLONESHOT.\n:\n: b. When a thread wants to delete a file descriptor, it\n: should do the following:\n:\n: [1] Call epoll_ctl(EPOLL_CTL_DISABLE)\n: [2] If the return status from epoll_ctl(EPOLL_CTL_DISABLE)\n: was zero, then the file descriptor can be safely\n: deleted by the thread that made this call.\n: [3] If the epoll_ctl(EPOLL_CTL_DISABLE) fails with EBUSY,\n: then the descriptor is in use. In this case, the calling\n: thread should set a flag in the user-space cache to\n: indicate that the thread that is using the descriptor\n: should perform the deletion operation.\n:\n: Is all of the above correct?\n:\n: The implementation depends on checking on whether\n: (events \u0026 ~EP_PRIVATE_BITS) \u003d\u003d 0\n: This replies on the fact that EPOLL_CTL_AD and EPOLL_CTL_MOD always\n: set EPOLLHUP and EPOLLERR in the \u0027events\u0027 mask, and EPOLLONESHOT\n: causes those flags (as well as all others in ~EP_PRIVATE_BITS) to be\n: cleared.\n:\n: A corollary to the previous paragraph is that using EPOLL_CTL_DISABLE\n: is only useful in conjunction with EPOLLONESHOT. However, as things\n: stand, one can use EPOLL_CTL_DISABLE on a file descriptor that does\n: not have EPOLLONESHOT set in \u0027events\u0027 This results in the following\n: (slightly surprising) behavior:\n:\n: (a) The first call to epoll_ctl(EPOLL_CTL_DISABLE) returns 0\n: (the indicator that the file descriptor can be safely deleted).\n: (b) The next call to epoll_ctl(EPOLL_CTL_DISABLE) fails with EBUSY.\n:\n: This doesn\u0027t seem particularly useful, and in fact is probably an\n: indication that the user made a logic error: they should only be using\n: epoll_ctl(EPOLL_CTL_DISABLE) on a file descriptor for which\n: EPOLLONESHOT was set in \u0027events\u0027. If that is correct, then would it\n: not make sense to return an error to user space for this case?\n\nCc: Michael Kerrisk \u003cmtk.manpages@gmail.com\u003e\nCc: \"Paton J.

By confining all those renames there at 3.7\n it will cause all the harm at for media developers on just one\n shot. Stable backports upstream and at distros will likely\n welcome it as well, as they won\u0027t need to check what changed on\n 3.7 and what was postponed for on 3.8.\n\n 2) The V4L2 DocBook Makefile creates a cross-reference between the\n media API headers and the specs. This helps us _a_lot_ to be sure\n that all API improvements are properly documented. Every time a\n header changes from one place to another, DocBook/media/Makefile\n needs to be patched.
