  "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",
