In addition, eMMC v4.4\ncards can support secure erase, trim and secure trim operations that are\nall variants of the basic erase command.\n\nSD/MMC device attributes \"erase_size\" and \"preferred_erase_size\" have been\nadded.\n\n\"erase_size\" is the minimum size, in bytes, of an erase operation. For\nMMC, \"erase_size\" is the erase group size reported by the card. Note that\n\"erase_size\" does not apply to trim or secure trim operations where the\nminimum size is always one 512 byte sector. For SD, \"erase_size\" is 512\nif the card is block-addressed, 0 otherwise.\n\nSD/MMC cards can erase an arbitrarily large area up to and\nincluding the whole card. When erasing a large area it may\nbe desirable to do it in smaller chunks for three reasons:\n\n 1. A single erase command will make all other I/O on the card\n wait. This is not a problem if the whole card is being erased, but\n erasing one partition will make I/O for another partition on the\n same card wait for the duration of the erase - which could be a\n several minutes.\n\n 2. To be able to inform the user of erase progress.\n\n 3. The erase timeout becomes too large to be very useful.\n Because the erase timeout contains a margin which is multiplied by\n the size of the erase area, the value can end up being several\n minutes for large areas.\n\n\"erase_size\" is not the most efficient unit to erase (especially for SD\nwhere it is just one sector), hence \"preferred_erase_size\" provides a good\nchunk size for erasing large areas.\n\nFor MMC, \"preferred_erase_size\" is the high-capacity erase size if a card\nspecifies one, otherwise it is based on the capacity of the card.\n\nFor SD, \"preferred_erase_size\" is the allocation unit size specified by\nthe card.\n\n\"preferred_erase_size\" is in bytes.\n\nSigned-off-by: Adrian Hunter \u003cadrian.hunter@nokia.com\u003e\nAcked-by: Jens Axboe \u003caxboe@kernel.dk\u003e\nCc: Kyungmin Park \u003ckmpark@infradead.org\u003e\nCc: Madhusudhan Chikkature \u003cmadhu.cr@ti.com\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Ben Gardiner \u003cbengardiner@nanometrics.ca\u003e\nCc: \u003clinux-mmc@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "81d73a32d775ae9674ea6edf0b5b721fc3bc57d9", "tree": "c4097c3c7715a128cf54252b2ff906d3d8946ae0", "parents": [ "a50aeb40144982eb766053309b6fc33e14ca46f0" ], "author": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Wed Aug 11 14:17:44 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Aug 12 08:43:30 2010 -0700" }, "message": "mm: fix writeback_in_progress()\n\nCommit 83ba7b071f3 (\"writeback: simplify the write back thread queue\")\nbroke writeback_in_progress() as in that commit we started to remove work\nitems from the list at the moment we start working on them and not at the\nmoment they are finished. Thus if the flusher thread was doing some work\nbut there was no other work queued, writeback_in_progress() returned\nfalse. This could in particular cause unnecessary queueing of background\nwriteback from balance_dirty_pages() or writeout work from\nwriteback_sb_if_idle().\n\nThis patch fixes the problem by introducing a bit in the bdi state which\nindicates that the flusher thread is processing some work and uses this\nbit for writeback_in_progress() test.\n\nNOTE: Both callsites of writeback_in_progress() (namely,\nwriteback_inodes_sb_if_idle() and balance_dirty_pages()) would actually\nneed a different information than what writeback_in_progress() provides.\nThey would need to know whether *the kind of writeback they are going to\nsubmit* is already queued.

The URBs have to be unlinked when the root hub is unregistered,\nand uhci-hcd relies upon root-hub status polls as part of its\nunlinking procedure. But usb_hcd_poll_rh_status() won\u0027t make those\nstatus calls if hcd-\u003erh_registered is clear, and the flag is cleared\n_before_ the unregistration takes place.\n\nSince hcd-\u003erh_registered is used for other things and needs to be\ncleared early, the solution is to add a new flag (rh_pollable) and use\nit instead. It gets cleared _after_ the root hub is unregistered.\n\nNow that the status polls don\u0027t end too soon, we have to make sure\nthey also don\u0027t occur too late -- after the root hub\u0027s usb_device\nstructure or the HCD\u0027s private structures are deallocated.

This allows the process on the server side of the pty\n to know when the state of the terminal has changed; it can then\n issue the appropriate ioctl to retrieve the new state.\n\nSince the original BSD patches accompanied the source code for telnet\nI\u0027ve left that reference here, but obviously the feature is useful for\nany remote terminal protocol, including ssh.\n\nThe corresponding feature has existed in the BSD tty driver since 1989.\nFor historical reference, a good copy of the relevant files can be found\nhere:\n\nhttp://anonsvn.mit.edu/viewvc/krb5/trunk/src/appl/telnet/?pathrev\u003d17741\n\nSigned-off-by: Howard Chu \u003chyc@symas.com\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n\n" }, { "commit": "39e5322c074f895b5b5c657a312c56b6c6154a38", "tree": "ca4ed9e999559f3ac96007a23d7c95228160df37", "parents": [ "d6e679b474c096f1125087e789e7af8886de39d3" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Thu Jun 17 15:15:16 2010 -0400" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Tue Aug 10 13:47:39 2010 -0700" }, "message": "tty: Remove Hayes ESP ioctls\n\nRemove Hayes ESP ioctls\n\nThe Hayes ESP driver has been removed from the tree:\ncommit f53a2ade0bb9f2a81f473e6469155172a96b7c38\n(\"tty: esp: remove broken driver\")\nso its ioctls aren\u0027t needed any more.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nAcked-by: Alan Cox \u003calan@linux.intel.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "b34d8915c413acb51d837a45fb8747b61f65c020", "tree": "ced5fac166324634653d84b1afe2b958b3904f4d", "parents": [ "e8a89cebdbaab14caaa26debdb4ffd493b8831af", "f33ebbe9da2c3c24664a0ad4f8fd83f293547e63" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Aug 10 12:07:51 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Aug 10 12:07:51 2010 -0700" }, "message": "Merge branch \u0027writable_limits\u0027 of git://decibel.fi.muni.cz/~xslaby/linux\n\n* \u0027writable_limits\u0027 of git://decibel.fi.muni.cz/~xslaby/linux:\n unistd: add __NR_prlimit64 syscall numbers\n rlimits: implement prlimit64 syscall\n rlimits: switch more rlimit syscalls to do_prlimit\n rlimits: redo do_setrlimit to more generic do_prlimit\n rlimits: add rlimit64 structure\n rlimits: do security check under task_lock\n rlimits: allow setrlimit to non-current tasks\n rlimits: split sys_setrlimit\n rlimits: selinux, do rlimits changes under task_lock\n rlimits: make sure -\u003erlim_max never grows in sys_setrlimit\n rlimits: add task_struct to update_rlimit_cpu\n rlimits: security, add task_struct to setrlimit\n\nFix up various system call number conflicts.

As a consequence, the cpuidle states that the SoC is safe to\nenter can change from idle period to idle period. In addition, the\nlatency and threshold of each cpuidle state can vary, depending on the\noperating condition when the CPU becomes idle, e.g. the current cpu\nfrequency, the current state of the HW blocks, etc.\n\ncpuidle core and the menu governor, in the current form, are geared\ntowards cpuidle states that are static, i.e. the availabiltiy of the\nstates, their latencies, their thresholds are non-changing during run\ntime. cpuidle does not provide any hook that cpuidle drivers can use to\nadjust those values on the fly for the current idle period before the menu\ngovernor selects the target cpuidle state.\n\nThis patch extends cpuidle core and the menu governor to handle states\nthat are dynamic. There are three additions in the patch and the patch\nmaintains backwards-compatibility with existing cpuidle drivers.\n\n1) add prepare() to struct cpuidle_device. A cpuidle driver can hook\n into the callback and cpuidle will call prepare() before calling the\n governor\u0027s select function. The callback gives the cpuidle driver a\n chance to update the dynamic information of the cpuidle states for the\n current idle period, e.g. state availability, latencies, thresholds,\n power values, etc.\n\n2) add CPUIDLE_FLAG_IGNORE as one of the state flags. In the prepare()\n function, a cpuidle driver can set/clear the flag to indicate to the\n menu governor whether a cpuidle state should be ignored, i.e. not\n available, during the current idle period.\n\n3) add power_specified bit to struct cpuidle_device. The menu governor\n currently assumes that the cpuidle states are arranged in the order of\n increasing latency, threshold, and power savings. This is true or can\n be made true for static states. Once the state parameters are dynamic,\n the latencies, thresholds, and power savings for the cpuidle states can\n increase or decrease by different amounts from idle period to idle\n period. So the assumption of increasing latency, threshold, and power\n savings from Cn to C(n+1) can no longer be guaranteed.\n\nIt can be straightforward to calculate the power consumption of each\navailable state and to specify it in power_usage for the idle period.\nUsing the power_usage fields, the menu governor then selects the state\nthat has the lowest power consumption and that still satisfies all other\ncritieria. The power_specified bit defaults to 0. For existing cpuidle\ndrivers, cpuidle detects that power_specified is 0 and fills in a dummy\nset of power_usage values.\n\nSigned-off-by: Ai Li \u003caili@codeaurora.org\u003e\nCc: Len Brown \u003clen.brown@intel.com\u003e\nAcked-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Venkatesh Pallipadi \u003cvenki@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d2997b1042ec150616c1963b5e5e919ffd0b0ebf", "tree": "c970746ad3d5c3e0ccbd1695d07144dbe4534ec4", "parents": [ "966cca029f739716fbcc8068b8c6dfe381f86fc3" ], "author": { "name": "KAMEZAWA Hiroyuki", "email": "kamezawa.hiroyu@jp.fujitsu.com", "time": "Mon Aug 09 17:20:11 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Aug 09 20:45:04 2010 -0700" }, "message": "hibernation: freeze swap at hibernation\n\nWhen taking a memory snapshot in hibernate_snapshot(), all (directly\ncalled) memory allocations use GFP_ATOMIC.

The goal is to\nmake it as simple and predictable as possible so the results are better\nunderstood and we end up killing the task which will lead to the most\nmemory freeing while still respecting the fine-tuning from userspace.\n\nInstead of basing the heuristic on mm-\u003etotal_vm for each task, the task\u0027s\nrss and swap space is used instead. This is a better indication of the\namount of memory that will be freeable if the oom killed task is chosen\nand subsequently exits. This helps specifically in cases where KDE or\nGNOME is chosen for oom kill on desktop systems instead of a memory\nhogging task.\n\nThe baseline for the heuristic is a proportion of memory that each task is\ncurrently using in memory plus swap compared to the amount of \"allowable\"\nmemory. \"Allowable,\" in this sense, means the system-wide resources for\nunconstrained oom conditions, the set of mempolicy nodes, the mems\nattached to current\u0027s cpuset, or a memory controller\u0027s limit. The\nproportion is given on a scale of 0 (never kill) to 1000 (always kill),\nroughly meaning that if a task has a badness() score of 500 that the task\nconsumes approximately 50% of allowable memory resident in RAM or in swap\nspace.\n\nThe proportion is always relative to the amount of \"allowable\" memory and\nnot the total amount of RAM systemwide so that mempolicies and cpusets may\noperate in isolation; they shall not need to know the true size of the\nmachine on which they are running if they are bound to a specific set of\nnodes or mems, respectively.\n\nRoot tasks are given 3% extra memory just like __vm_enough_memory()\nprovides in LSMs. In the event of two tasks consuming similar amounts of\nmemory, it is generally better to save root\u0027s task.\n\nBecause of the change in the badness() heuristic\u0027s baseline, it is also\nnecessary to introduce a new user interface to tune it. It\u0027s not possible\nto redefine the meaning of /proc/pid/oom_adj with a new scale since the\nABI cannot be changed for backward compatability. Instead, a new tunable,\n/proc/pid/oom_score_adj, is added that ranges from -1000 to +1000. It may\nbe used to polarize the heuristic such that certain tasks are never\nconsidered for oom kill while others may always be considered. The value\nis added directly into the badness() score so a value of -500, for\nexample, means to discount 50% of its memory consumption in comparison to\nother tasks either on the system, bound to the mempolicy, in the cpuset,\nor sharing the same memory controller.\n\n/proc/pid/oom_adj is changed so that its meaning is rescaled into the\nunits used by /proc/pid/oom_score_adj, and vice versa.

Then it can be removed\nsafely. It reduce stack usage slightly.\n\nNow I have to say that I\u0027m sorry. 2 years ago, I thought prev_priority\ncan be integrate again, it\u0027s useful. but four (or more) times trying\nhaven\u0027t got good performance number. Thus I give up such approach.\n\nThe rest of this changelog is notes on prev_priority and why it existed in\nthe first place and why it might be not necessary any more. This information\nis based heavily on discussions between Andrew Morton, Rik van Riel and\nKosaki Motohiro who is heavily quotes from.\n\nHistorically prev_priority was important because it determined when the VM\nwould start unmapping PTE pages. i.e. there are no balances of note within\nthe VM, Anon vs File and Mapped vs Unmapped. Without prev_priority, there\nis a potential risk of unnecessarily increasing minor faults as a large\namount of read activity of use-once pages could push mapped pages to the\nend of the LRU and get unmapped.\n\nThere is no proof this is still a problem but currently it is not considered\nto be. Active files are not deactivated if the active file list is smaller\nthan the inactive list reducing the liklihood that file-mapped pages are\nbeing pushed off the LRU and referenced executable pages are kept on the\nactive list to avoid them getting pushed out by read activity.\n\nEven if it is a problem, prev_priority prev_priority wouldn\u0027t works\nnowadays. First of all, current vmscan still a lot of UP centric code. it\nexpose some weakness on some dozens CPUs machine. I think we need more and\nmore improvement.\n\nThe problem is, current vmscan mix up per-system-pressure, per-zone-pressure\nand per-task-pressure a bit. example, prev_priority try to boost priority to\nother concurrent priority. but if the another task have mempolicy restriction,\nit is unnecessary, but also makes wrong big latency and exceeding reclaim.\nper-task based priority + prev_priority adjustment make the emulation of\nper-system pressure. but it have two issue 1) too rough and brutal emulation\n2) we need per-zone pressure, not per-system.\n\nAnother example, currently DEF_PRIORITY is 12. it mean the lru rotate about\n2 cycle (1/4096 + 1/2048 + 1/1024 + .. + 1) before invoking OOM-Killer.\nbut if 10,0000 thrreads enter DEF_PRIORITY reclaim at the same time, the\nsystem have higher memory pressure than priority\u003d\u003d0 (1/4096*10,000 \u003e 2).\nprev_priority can\u0027t solve such multithreads workload issue. In other word,\nprev_priority concept assume the sysmtem don\u0027t have lots threads.\"\n\nSigned-off-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nReviewed-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nReviewed-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: Dave Chinner \u003cdavid@fromorbit.com\u003e\nCc: Chris Mason \u003cchris.mason@oracle.com\u003e\nCc: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: Michael Rubin \u003cmrubin@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "755f0225e8347b23a33ee6e3fb14a35310f95766", "tree": "23489e9f52f1435c7b8bc4da8e98d607460e4e23", "parents": [ "a8a94d151521b248727c1f88756174e15260815a" ], "author": { "name": "Mel Gorman", "email": "mel@csn.ul.ie", "time": "Mon Aug 09 17:19:18 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Aug 09 20:45:00 2010 -0700" }, "message": "vmscan: tracing: add trace event when a page is written\n\nAdd a trace event for when page reclaim queues a page for IO and records\nwhether it is synchronous or asynchronous.
