This causes any update to a set of\nallowed nodes to stall until put_mems_allowed() is called.\n\nThis stall is unncessary, however, if at least one node remains unchanged\nin the update to the set of allowed nodes. This was addressed by\n89e8a244b97e (\"cpusets: avoid looping when storing to mems_allowed if one\nnode remains set\"), but it\u0027s still possible that an empty nodemask may be\nread from a mempolicy because the old nodemask may be remapped to the new\nnodemask during rebind. To prevent this, only avoid the stall if there is\nno mempolicy for the thread being changed.\n\nThis is a temporary solution until all reads from mempolicy nodemasks can\nbe guaranteed to not be empty without the get_mems_allowed()\nsynchronization.\n\nAlso moves the check for nodemask intersection inside task_lock() so that\ntsk-\u003emems_allowed cannot change. This ensures that nothing can set this\ntsk\u0027s mems_allowed out from under us and also protects tsk-\u003emempolicy.\n\nReported-by: Miao Xie \u003cmiaox@cn.fujitsu.com\u003e\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Paul Menage \u003cpaul@paulmenage.org\u003e\nCc: Stephen Rothwell \u003csfr@canb.auug.org.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "45aa0663cc408617b79a2b53f0a5f50e94688a48", "tree": "0a53931c317c3c72a3555bd2fbb70a881ee870f2", "parents": [ "511585a28e5b5fd1cac61e601e42efc4c5dd64b5", "7bd0b0f0da3b1ec11cbcc798eb0ef747a1184077" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Dec 20 12:14:26 2011 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Dec 20 12:14:26 2011 +0100" }, "message": "Merge branch \u0027memblock-kill-early_node_map\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc into core/memblock\n" }, { "commit": "612ef28a045efadb3a98d4492ead7806a146485d", "tree": "05621c87b37e91c27b06d450d76adffe97ce9666", "parents": [ "c3e0ef9a298e028a82ada28101ccd5cf64d209ee", "07cde2608a3b5c66515363f1b53623b1536b9785" ], "author": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Mon Dec 19 19:23:15 2011 +0100" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Mon Dec 19 19:23:15 2011 +0100" }, "message": "Merge branch \u0027sched/core\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip into cputime-tip\n\nConflicts:\n\tdrivers/cpufreq/cpufreq_conservative.c\n\tdrivers/cpufreq/cpufreq_ondemand.c\n\tdrivers/macintosh/rack-meter.c\n\tfs/proc/stat.c\n\tfs/proc/uptime.c\n\tkernel/sched/core.c\n" }, { "commit": "29e21368b9baf9c4b25060d65062da2dda926c70", "tree": "eb0d51c03f63b78317dbe329245ce7e40cb2261d", "parents": [ "52dcf8a1f8ac09b6ea21266ebdc4db6d52eea1fc" ], "author": { "name": "Mandeep Singh Baines", "email": "msb@chromium.org", "time": "Thu Dec 15 14:21:26 2011 -0800" }, "committer": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Mon Dec 19 09:14:30 2011 -0800" }, "message": "cgroups: remove redundant get/put of css_set from css_set_check_fetched()\n\nWe already have a reference to all elements in newcg_list.\n\nSigned-off-by: Mandeep Singh Baines \u003cmsb@chromium.org\u003e\nReviewed-by: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: containers@lists.linux-foundation.org\nCc: cgroups@vger.kernel.org\nCc: Paul Menage \u003cpaul@paulmenage.org\u003e\n" }, { "commit": "e0197aae59e55c06db172bfbe1a1cdb8c0e1cab3", "tree": "c3b36f2adc445893166bc5caddb3d26c05611a9a", "parents": [ "390f998509bf049019df0b078c0a6606e0d57fb4" ], "author": { "name": "Mandeep Singh Baines", "email": "msb@chromium.org", "time": "Thu Dec 15 11:36:43 2011 -0800" }, "committer": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Mon Dec 19 09:09:09 2011 -0800" }, "message": "cgroups: fix a css_set not found bug in cgroup_attach_proc\n\nThere is a BUG when migrating a PF_EXITING proc.
