Targeted async\ndraining has been introduced by 26fe6168 (memcg: fix percpu cached\ncharge draining frequency) to reduce the cpu workers number.\n\nsync draining is currently triggered only from mem_cgroup_force_empty\nwhich is triggered only by userspace (mem_cgroup_force_empty_write) or\nwhen a cgroup is removed (mem_cgroup_pre_destroy). Although these are\nnot usually frequent operations it still makes some sense to do targeted\ndraining as well, especially if the box has many CPUs.\n\nThis patch unifies both methods to use the single code (drain_all_stock)\nwhich relies on the original async implementation and just adds\nflush_work to wait on all caches that are still under work for the sync\nmode.

While A releases the mutex and\ncalls mem_cgroup_out_of_memory others will wake up (one after another)\nand increase the counter and fall into sleep (memcg_oom_waitq).\n\nOnce A finishes mem_cgroup_out_of_memory it takes the mutex again and\ndecreases oom_lock and wakes other tasks (if releasing memory by\nsomebody else - e.g. killed process - hasn\u0027t done it yet).\n\nA testcase would look like:\n Assume malloc XXX is a program allocating XXX Megabytes of memory\n which touches all allocated pages in a tight loop\n # swapoff SWAP_DEVICE\n # cgcreate -g memory:A\n # cgset -r memory.oom_control\u003d0 A\n # cgset -r memory.limit_in_bytes\u003d 200M\n # for i in `seq 100`\n # do\n # cgexec -g memory:A malloc 10 \u0026\n # done\n\nThe main problem here is that all processes still race for the mutex and\nthere is no guarantee that we will get counter back to 0 for those that\ngot back to mem_cgroup_handle_oom. In the end the whole convoy\nin/decreases the counter but we do not get to 1 that would enable\nkilling so nothing useful can be done. The time is basically unbounded\nbecause it highly depends on scheduling and ordering on mutex (I have\nseen this taking hours...).\n\nThis patch replaces the counter by a simple {un}lock semantic. As\nmem_cgroup_oom_{un}lock works on the a subtree of a hierarchy we have to\nmake sure that nobody else races with us which is guaranteed by the\nmemcg_oom_mutex.\n\nWe have to be careful while locking subtrees because we can encounter a\nsubtree which is already locked: hierarchy:\n\n A\n / \\\n B \\\n /\\ \\\n C D E\n\nB - C - D tree might be already locked. While we want to enable locking\nE subtree because OOM situations cannot influence each other we\ndefinitely do not want to allow locking A.\n\nTherefore we have to refuse lock if any subtree is already locked and\nclear up the lock for all nodes that have been set up to the failure\npoint.\n\nOn the other hand we have to make sure that the rest of the world will\nrecognize that a group is under OOM even though it doesn\u0027t have a lock.\nTherefore we have to introduce under_oom variable which is incremented\nand decremented for the whole subtree when we enter resp. leave\nmem_cgroup_handle_oom. under_oom, unlike oom_lock, doesn\u0027t need be\nupdated under memcg_oom_mutex because its users only check a single\ngroup and they use atomic operations for that.\n\nThis can be checked easily by the following test case:\n\n # cgcreate -g memory:A\n # cgset -r memory.use_hierarchy\u003d1 A\n # cgset -r memory.oom_control\u003d1 A\n # cgset -r memory.limit_in_bytes\u003d 100M\n # cgset -r memory.memsw.limit_in_bytes\u003d 100M\n # cgcreate -g memory:A/B\n # cgset -r memory.oom_control\u003d1 A/B\n # cgset -r memory.limit_in_bytes\u003d20M\n # cgset -r memory.memsw.limit_in_bytes\u003d20M\n # cgexec -g memory:A/B malloc 30 \u0026 #-\u003ethis will be blocked by OOM of group B\n # cgexec -g memory:A malloc 80 \u0026 #-\u003ethis will be blocked by OOM of group A\n\nWhile B gets oom_lock A will not get it. Both of them go into sleep and\nwait for an external action. We can make the limit higher for A to\nenforce waking it up\n\n # cgset -r memory.memsw.limit_in_bytes\u003d300M A\n # cgset -r memory.limit_in_bytes\u003d300M A\n\nmalloc in A has to wake up even though it doesn\u0027t have oom_lock.\n\nFinally, the unlock path is very easy because we always unlock only the\nsubtree we have locked previously while we always decrement under_oom.\n\nSigned-off-by: Michal Hocko \u003cmhocko@suse.cz\u003e\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Balbir Singh \u003cbsingharora@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "bb2a0de92c891b8feeedc0178acb3ae009d899a8", "tree": "c2c0b3ad66c8da0e48c021927b2d747fb08b7ef3", "parents": [ "1f4c025b5a5520fd2571244196b1b01ad96d18f6" ], "author": { "name": "KAMEZAWA Hiroyuki", "email": "kamezawa.hiroyu@jp.fujitsu.com", "time": "Tue Jul 26 16:08:22 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jul 26 16:49:42 2011 -0700" }, "message": "memcg: consolidate memory cgroup lru stat functions\n\nIn mm/memcontrol.c, there are many lru stat functions as..\n\n mem_cgroup_zone_nr_lru_pages\n mem_cgroup_node_nr_file_lru_pages\n mem_cgroup_nr_file_lru_pages\n mem_cgroup_node_nr_anon_lru_pages\n mem_cgroup_nr_anon_lru_pages\n mem_cgroup_node_nr_unevictable_lru_pages\n mem_cgroup_nr_unevictable_lru_pages\n mem_cgroup_node_nr_lru_pages\n mem_cgroup_nr_lru_pages\n mem_cgroup_get_local_zonestat\n\nSome of them are under #ifdef MAX_NUMNODES \u003e1 and others are not.\nThis seems bad.

(The downside of this approach is that\nthese resources cannot be used as templates for setting the actual\ndevice\u0027s resources because they are missing from the template.) The\nkernel\u0027s APM implementation does not suffer from this problem and\nregisters all resources regardless of \"their size\".\n\nThis patch fixes a problem with (at least) the vintage IBM ThinkPad 600E\n(and most likely also with the 600, 600X, and 770X which have a very\nsimilar layout) where some of its PnP devices support options where\neither an IRQ, a DMA, or an IO port is disabled. Without this patch,\nthe devices can not be configured using the\n\"/sys/bus/pnp/devices/*/resources\" interface.\n\nThe manipulation of these resources is important because the 600E has\nvery demanding requirements. For instance, the number of IRQs is not\nsufficient to support all devices of the 600E. Fortunately, some of the\ndevices, like the sound card\u0027s MPU-401 UART, can be configured to not\nuse any IRQ, hence freeing an IRQ for a device that requires one.\n(Still, the device\u0027s \"ResourceTemplate\" requires an IRQ resource\ndescriptor which cannot be created if the resource has not been\nregistered in the first place.)\n\nAs an example, the dependent sets of the 600E\u0027s CSC0103 device (the\nMPU-401 UART) are listed, with the patch applied, as:\n\n Dependent: 00 - Priority preferred\n port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding\n irq \u003cnone\u003e High-Edge\n Dependent: 01 - Priority acceptable\n port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding\n irq 5,7,2/9,10,11,15 High-Edge\n\n(The same result is obtained when PNPBIOS is used instead of PnP ACPI.)\nWithout the patch, the IRQ resource in the preferred option is not\nlisted at all:\n\n Dependent: 00 - Priority preferred\n port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding\n Dependent: 01 - Priority acceptable\n port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding\n irq 5,7,2/9,10,11,15 High-Edge\n\nAnd in fact, the 600E\u0027s DSDT lists the disabled IRQ as an option, as can\nbe seen from the following excerpt from the DSDT:\n\n\tName (_PRS, ResourceTemplate ()\n\t{\n StartDependentFn (0x00, 0x00)\n {\n IO (Decode16, 0x0300, 0x0330, 0x10, 0x04)\n IRQNoFlags () {}\n }\n StartDependentFn (0x01, 0x00)\n {\n IO (Decode16, 0x0300, 0x0330, 0x10, 0x04)\n IRQNoFlags () {5,7,9,10,11,15}\n }\n EndDependentFn ()\n\t})\n\nWith this patch applied, a user space program - or maybe even the kernel\n- can allocate all devices\u0027 resources optimally. For the 600E, this\nmeans to find optimal resources for (at least) the serial port, the\nparallel port, the infrared port, the MWAVE modem, the sound card, and\nthe MPU-401 UART.\n\nThe patch applies the idea to register disabled resources to all types\nof resources, not just to IRQs, DMAs, and IO ports. At the same time,\nit mimics the behavior of the \"pnp_assign_xxx\" functions from\n\"drivers/pnp/manager.c\" where resources with \"no size\" are considered\ndisabled.\n\nNo regressions were observed on hardware that does not require this\npatch.\n\nThe patch is applied against 2.6.39.\n\nNB: The kernel\u0027s current PnP interface does not allow for disabling individual\nresources using the \"/sys/bus/pnp/devices/$device/resources\" file. Assuming\nthis could be done, a device could be configured to use a disabled resource\nusing a simple series of calls:\n\n echo disable \u003e /sys/bus/pnp/devices/$device/resources\n echo clear \u003e /sys/bus/pnp/devices/$device/resources\n echo set irq disabled \u003e /sys/bus/pnp/devices/$device/resources\n echo fill \u003e /sys/bus/pnp/devices/$device/resources\n echo activate \u003e /sys/bus/pnp/devices/$device/resources\n\nThis patch addresses only the parsing of PnP ACPI devices.\n\nChangeLog (v1 -\u003e v2):\n - extend patch description\n - fix typo in patch itself\n\nSigned-off-by: Witold Szczeponik \u003cWitold.Szczeponik@gmx.net\u003e\nCc: Len Brown \u003clenb@kernel.org\u003e\nCc: Adam Belay \u003cabelay@mit.edu\u003e\nCc: Bjorn Helgaas \u003cbjorn.helgaas@hp.com\u003e\nCc: Bjorn Helgaas \u003cbhelgaas@google.com\u003e\nCc: Henrique de Moraes Holschuh \u003chmh@hmh.eng.br\u003e\nCc: Matthew Garrett \u003cmjg@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e57ee01750c4954fd0b5e3c6109cd4b870880eb9", "tree": "73356d5604cc10ca8e6e86616276da4531984004", "parents": [ "8f6b0dd369868559b384a66aa17512ae5aae2d9b" ], "author": { "name": "Uwe Kleine-König", "email": "u.kleine-koenig@pengutronix.de", "time": "Mon Jul 25 17:13:34 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 20:57:17 2011 -0700" }, "message": "drivers/rtc/rtc-tegra.c: properly initialize spinlock\n\nUsing __SPIN_LOCK_UNLOCKED for a dynamically allocated lock is wrong and\nbreaks the build with PREEMPT_RT_FULL.\n\nSigned-off-by: Uwe Kleine-König \u003cu.kleine-koenig@pengutronix.de\u003e\nCc: Andrew Chew \u003cachew@nvidia.com\u003e\nCc: \u003cstable@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": "8f6b0dd369868559b384a66aa17512ae5aae2d9b", "tree": "b98bcc40d158d96fe30af93e5bdede28fbeac77d", "parents": [ "9a9a54ad7aa2c7420c96c6fd33538f55d81775cb" ], "author": { "name": "Jesper Juhl", "email": "jj@chaosbits.net", "time": "Mon Jul 25 17:13:34 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Jul 25 20:57:17 2011 -0700" }, "message": "drivers/rtc/rtc-twl.c: check return value of twl_rtc_write_u8() in twl_rtc_set_time()\n\nWe forget to save the return value of the call to\ntwl_rtc_write_u8(save_control, REG_RTC_CTRL_REG); in \u0027ret\u0027, making the\ntest of \u0027ret \u003c 0\u0027 dead code since \u0027ret\u0027 then couldn\u0027t possibly have\nchanged since the last test just a few lines above.
