It is not atypical to see writes to\ncpuset.mems take over 2 seconds to complete, for example. In low memory\nconditions, this is problematic because it\u0027s one of the most imporant\ntimes to change cpuset.mems in the first place!\n\nThe only way a task\u0027s set of allowable nodes may change is through cpusets\nby writing to cpuset.mems and when attaching a task to a generic code is\nnot reading the nodemask with get_mems_allowed() at the same time, and\nthen clearing all the old nodes. This prevents the possibility that a\nreader will see an empty nodemask at the same time the writer is storing a\nnew nodemask.\n\nIf at least one node remains unchanged, though, it\u0027s possible to simply\nset all new nodes and then clear all the old nodes. Changing a task\u0027s\nnodemask is protected by cgroup_mutex so it\u0027s guaranteed that two threads\nare not changing the same task\u0027s nodemask at the same time, so the\nnodemask is guaranteed to be stored before another thread changes it and\ndetermines whether a node remains set or not.\n\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nCc: Miao Xie \u003cmiaox@cn.fujitsu.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Nick Piggin \u003cnpiggin@kernel.dk\u003e\nCc: Paul Menage \u003cpaul@paulmenage.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "77ceab8ea590d7dc6c8f055ce43dfebd74428107", "tree": "b2ef5e5baca4579565ab9bf527e965dd9b93a25a", "parents": [ "33ef6b6984403a688189317ef46bb3caab3b70e0" ], "author": { "name": "Ben Blum", "email": "bblum@andrew.cmu.edu", "time": "Wed Nov 02 13:38:07 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Nov 02 16:06:59 2011 -0700" }, "message": "cgroups: don\u0027t attach task to subsystem if migration failed\n\nIf a task has exited to the point it has called cgroup_exit() already,\nthen we can\u0027t migrate it to another cgroup anymore.\n\nThis can happen when we are attaching a task to a new cgroup between the\ncall to -\u003ecan_attach_task() on subsystems and the migration that is\neventually tried in cgroup_task_migrate().\n\nIn this case cgroup_task_migrate() returns -ESRCH and we don\u0027t want to\nattach the task to the subsystems because the attachment to the new cgroup\nitself failed.\n\nFix this by only calling -\u003eattach_task() on the subsystems if the cgroup\nmigration succeeded.\n\nReported-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nSigned-off-by: Ben Blum \u003cbblum@andrew.cmu.edu\u003e\nAcked-by: Paul Menage \u003cpaul@paulmenage.org\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@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": "33ef6b6984403a688189317ef46bb3caab3b70e0", "tree": "43dff6dd0150b34ce69b1d681c92659c9b20eb5c", "parents": [ "434a964daa14b9db083ce20404a4a2add54d037a" ], "author": { "name": "Ben Blum", "email": "bblum@andrew.cmu.edu", "time": "Wed Nov 02 13:38:05 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Nov 02 16:06:59 2011 -0700" }, "message": "cgroups: more safe tasklist locking in cgroup_attach_proc\n\nFix unstable tasklist locking in cgroup_attach_proc.\n\nAccording to this thread - https://lkml.org/lkml/2011/7/27/243 - RCU is\nnot sufficient to guarantee the tasklist is stable w.r.t. de_thread and\nexit.

There is also a symmetrical ability to copy from the current\nprocess\u0027s address space into a destination process\u0027s address space.\n\n- Use of /proc/pid/mem has been considered, but there are issues with\n using it:\n - Does not allow for specifying iovecs for both src and dest, assuming\n preadv or pwritev was implemented either the area read from or\n written to would need to be contiguous.\n - Currently mem_read allows only processes who are currently\n ptrace\u0027ing the target and are still able to ptrace the target to read\n from the target. This check could possibly be moved to the open call,\n but its not clear exactly what race this restriction is stopping\n (reason appears to have been lost)\n - Having to send the fd of /proc/self/mem via SCM_RIGHTS on unix\n domain socket is a bit ugly from a userspace point of view,\n especially when you may have hundreds if not (eventually) thousands\n of processes that all need to do this with each other\n - Doesn\u0027t allow for some future use of the interface we would like to\n consider adding in the future (see below)\n - Interestingly reading from /proc/pid/mem currently actually\n involves two copies! (But this could be fixed pretty easily)\n\nAs mentioned previously use of vmsplice instead was considered, but has\nproblems. Since you need the reader and writer working co-operatively if\nthe pipe is not drained then you block. Which requires some wrapping to\ndo non blocking on the send side or polling on the receive. In all to all\ncommunication it requires ordering otherwise you can deadlock. And in the\nexample of many MPI tasks writing to one MPI task vmsplice serialises the\ncopying.\n\nThere are some cases of MPI collectives where even a single copy interface\ndoes not get us the performance gain we could. For example in an\nMPI_Reduce rather than copy the data from the source we would like to\ninstead use it directly in a mathops (say the reduce is doing a sum) as\nthis would save us doing a copy. We don\u0027t need to keep a copy of the data\nfrom the source. I haven\u0027t implemented this, but I think this interface\ncould in the future do all this through the use of the flags - eg could\nspecify the math operation and type and the kernel rather than just\ncopying the data would apply the specified operation between the source\nand destination and store it in the destination.\n\nAlthough we don\u0027t have a \"second user\" of the interface (though I\u0027ve had\nsome nibbles from people who may be interested in using it for intra\nprocess messaging which is not MPI). This interface is something which\nhardware vendors are already doing for their custom drivers to implement\nfast local communication. And so in addition to this being useful for\nOpenMPI it would mean the driver maintainers don\u0027t have to fix things up\nwhen the mm changes.\n\nThere was some discussion about how much faster a true zero copy would\ngo. Here\u0027s a link back to the email with some testing I did on that:\n\nhttp://marc.info/?l\u003dlinux-mm\u0026m\u003d130105930902915\u0026w\u003d2\n\nThere is a basic man page for the proposed interface here:\n\nhttp://ozlabs.org/~cyeoh/cma/process_vm_readv.txt\n\nThis has been implemented for x86 and powerpc, other architecture should\nmainly (I think) just need to add syscall numbers for the process_vm_readv\nand process_vm_writev. There are 32 bit compatibility versions for\n64-bit kernels.\n\nFor arch maintainers there are some simple tests to be able to quickly\nverify that the syscalls are working correctly here:\n\nhttp://ozlabs.org/~cyeoh/cma/cma-test-20110718.tgz\n\nSigned-off-by: Chris Yeoh \u003cyeohc@au1.ibm.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: \"H.

On s390\nit is possible to create kernel dumps with other dump mechanisms than kdump\n(e.g. via hypervisor dump or stand-alone dump tools). For those dumps it\nwould also be desirable to include the vmcoreinfo data. To accomplish this,\nwith this patch the vmcoreinfo ELF note is always initialized, not only in\ncase of a (kdump) crash. On s390 we will add an ABI defined pointer at\na well known address to vmcoreinfo so that dump analysis tools are able to\nfind this information.\n\nIn particular on s390 we have a tool named zgetdump. With this tool it is\npossible to convert dump formats on the fly using fuse. E.g. you can mount a\ns390 stand-alone dump as ELF dump. When this is done, the tool finds the\nvmcoreinfo in the stand-alone dump via the well known ABI defined address and\nit creates the respective VMCOREINFO ELF note in the output ELF dump. This then\ncan be used e.g. by makedumpfile for dump filtering. No more need for a\nvmlinux file with debug information.\n\nSo this will look like the following:\n$ zgetdump --mount standalone.dump -f elf /mnt\n$ ls /mnt\n dump.elf\n$ readelf -n /mnt/dump.elf\n$ ...\n VMCOREINFO 0x00000474 Unknown note type: (0x00000000)\n$ makedumpfile -c -d 31 /mnt/dump.elf dump.kdump\n\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nAcked-by: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nSigned-off-by: Michael Holzheu \u003cholzheu@linux.vnet.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "d3bf37955d46718ee1a7f1fc69f953d2328ba7c2", "tree": "a15c9bbb510c36dc5da870660dff9c2869920401", "parents": [ "3d214faea6e4f9b6018bf8589f4b245126349c0a" ], "author": { "name": "Michael Holzheu", "email": "holzheu@linux.vnet.ibm.com", "time": "Sun Oct 30 15:16:37 2011 +0100" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Sun Oct 30 15:16:41 2011 +0100" }, "message": "[S390] kdump: Add size to elfcorehdr kernel parameter\n\nCurrently only the address of the pre-allocated ELF header is passed with\nthe elfcorehdr\u003d kernel parameter.

Comparing with PC/notebook,\na mobile enters/exits suspend-2-ram (we call it s3 on Medfield) far\nmore frequently. If it can\u0027t enter suspend-2-ram in time, the power\nmight be used up soon.\n\nWe often find sometimes, a device suspend fails. Then, system retries\ns3 over and over again. As display is off, testers and developers\ndon\u0027t know what happens.\n\nSome testers and developers complain they don\u0027t know if system\ntries suspend-2-ram, and what device fails to suspend. They need\nsuch info for a quick check. The patch adds suspend_stats under\ndebugfs for users to check suspend to RAM statistics quickly.\n\nIf not using this patch, we have other methods to get info about\nwhat device fails. One is to turn on CONFIG_PM_DEBUG, but users\nwould get too much info and testers need recompile the system.\n\nIn addition, dynamic debug is another good tool to dump debug info.\nBut it still doesn\u0027t match our utilization scenario closely.\n1) user need write a user space parser to process the syslog output;\n2) Our testing scenario is we leave the mobile for at least hours.\n Then, check its status. No serial console available during the\n testing. One is because console would be suspended, and the other\n is serial console connecting with spi or HSU devices would consume\n power. These devices are powered off at suspend-2-ram.\n\nSigned-off-by: ShuoX Liu \u003cshuox.liu@intel.com\u003e\nSigned-off-by: Rafael J.
