It complicated matters by\nadding a second swap allocation path, just for hibernation; without in any\nway fixing the issue that it was intended to address - page reclaim after\nfixing the hibernation image might free swap from a page already imaged as\nswapcache, letting its swap be reallocated to store a different page of\nthe image: resulting in data corruption if the imaged page were freed as\nclean then swapped back in. Pages freed to si-\u003eswap_map were still in\ndanger of being reallocated by the alternative allocation path.\n\nI guess it inadvertently fixed slow SSD swap allocation for hibernation,\nas reported by Nigel Cunningham: by missing out the discards that occur on\nthe usual swap allocation path; but that was unintentional, and needs a\nseparate fix.\n\nSigned-off-by: Hugh Dickins \u003chughd@google.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: \"Rafael J.

First, if a wakeup\nevent occurs exactly when /sys/power/state is being written to, it\nmay be delivered to user space right before the freezer kicks in, so\nthe user space consumer of the event may not be able to process it\nbefore the system is suspended. Second, if a wakeup event occurs\nafter user space has been frozen, it is not generally guaranteed that\nthe ongoing transition of the system into a sleep state will be\naborted.\n\nTo address these issues introduce a new global sysfs attribute,\n/sys/power/wakeup_count, associated with a running counter of wakeup\nevents and three helper functions, pm_stay_awake(), pm_relax(), and\npm_wakeup_event(), that may be used by kernel subsystems to control\nthe behavior of this attribute and to request the PM core to abort\nsystem transitions into a sleep state already in progress.\n\nThe /sys/power/wakeup_count file may be read from or written to by\nuser space. Reads will always succeed (unless interrupted by a\nsignal) and return the current value of the wakeup events counter.\nWrites, however, will only succeed if the written number is equal to\nthe current value of the wakeup events counter. If a write is\nsuccessful, it will cause the kernel to save the current value of the\nwakeup events counter and to abort the subsequent system transition\ninto a sleep state if any wakeup events are reported after the write\nhas returned.\n\n[The assumption is that before writing to /sys/power/state user space\nwill first read from /sys/power/wakeup_count. Next, user space\nconsumers of wakeup events will have a chance to acknowledge or\nveto the upcoming system transition to a sleep state. Finally, if\nthe transition is allowed to proceed, /sys/power/wakeup_count will\nbe written to and if that succeeds, /sys/power/state will be written\nto as well. Still, if any wakeup events are reported to the PM core\nby kernel subsystems after that point, the transition will be\naborted.]\n\nAdditionally, put a wakeup events counter into struct dev_pm_info and\nmake these per-device wakeup event counters available via sysfs,\nso that it\u0027s possible to check the activity of various wakeup event\nsources within the kernel.\n\nTo illustrate how subsystems can use pm_wakeup_event(), make the\nlow-level PCI runtime PM wakeup-handling code use it.\n\nSigned-off-by: Rafael J.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "5a7aadfe2fcb0f69e2acc1fbefe22a096e792fc9", "tree": "dc1b649fc6aa05ecd25cab23e464894e660830d5", "parents": [ "4f598458ea4450f53e8ed929ee4e66b3404a7286" ], "author": { "name": "Matt Helsley", "email": "matthltc@us.ibm.com", "time": "Fri Mar 26 23:51:44 2010 +0100" }, "committer": { "name": "Rafael J.

Currently we test the cgroup freezer\nstate of the resuming tasks to see if the cgroup is FROZEN. If so\nthen we don\u0027t thaw the task. However, the FREEZING state also indicates\nthat the task should remain frozen.\n\nThis also avoids a problem pointed out by Oren Ladaan: the freezer state\ntransition from FREEZING to FROZEN is updated lazily when userspace reads\nor writes the freezer.state file in the cgroup filesystem. This means that\nresume will thaw tasks in cgroups which should be in the FROZEN state if\nthere is no read/write of the freezer.state file to trigger this\ntransition before suspend.\n\nNOTE: Another \"simple\" solution would be to always update the cgroup\nfreezer state during resume. However it\u0027s a bad choice for several reasons:\nUpdating the cgroup freezer state is somewhat expensive because it requires\nwalking all the tasks in the cgroup and checking if they are each frozen.\nWorse, this could easily make resume run in N^2 time where N is the number\nof tasks in the cgroup. Finally, updating the freezer state from this code\npath requires trickier locking because of the way locks must be ordered.\n\nInstead of updating the freezer state we rely on the fact that lazy\nupdates only manage the transition from FREEZING to FROZEN. We know that\na cgroup with the FREEZING state may actually be FROZEN so test for that\nstate too. This makes sense in the resume path even for partially-frozen\ncgroups -- those that really are FREEZING but not FROZEN.\n\nReported-by: Oren Ladaan \u003corenl@cs.columbia.edu\u003e\nSigned-off-by: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nCc: stable@kernel.org\nSigned-off-by: Rafael J.
