It provides a way to stop and resume execution of all tasks in\na cgroup by writing in the cgroup filesystem.\n\nThe freezer subsystem in the container filesystem defines a file named\nfreezer.state. Writing \"FROZEN\" to the state file will freeze all tasks\nin the cgroup. Subsequently writing \"RUNNING\" will unfreeze the tasks in\nthe cgroup. Reading will return the current state.\n\n* Examples of usage :\n\n # mkdir /containers/freezer\n # mount -t cgroup -ofreezer freezer /containers\n # mkdir /containers/0\n # echo $some_pid \u003e /containers/0/tasks\n\nto get status of the freezer subsystem :\n\n # cat /containers/0/freezer.state\n RUNNING\n\nto freeze all tasks in the container :\n\n # echo FROZEN \u003e /containers/0/freezer.state\n # cat /containers/0/freezer.state\n FREEZING\n # cat /containers/0/freezer.state\n FROZEN\n\nto unfreeze all tasks in the container :\n\n # echo RUNNING \u003e /containers/0/freezer.state\n # cat /containers/0/freezer.state\n RUNNING\n\nThis is the basic mechanism which should do the right thing for user space\ntask in a simple scenario.\n\nIt\u0027s important to note that freezing can be incomplete. In that case we\nreturn EBUSY. This means that some tasks in the cgroup are busy doing\nsomething that prevents us from completely freezing the cgroup at this\ntime. After EBUSY, the cgroup will remain partially frozen -- reflected\nby freezer.state reporting \"FREEZING\" when read. The state will remain\n\"FREEZING\" until one of these things happens:\n\n\t1) Userspace cancels the freezing operation by writing \"RUNNING\" to\n\t\tthe freezer.state file\n\t2) Userspace retries the freezing operation by writing \"FROZEN\" to\n\t\tthe freezer.state file (writing \"FREEZING\" is not legal\n\t\tand returns EIO)\n\t3) The tasks that blocked the cgroup from entering the \"FROZEN\"\n\t\tstate disappear from the cgroup\u0027s set of tasks.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: export thaw_process]\nSigned-off-by: Cedric Le Goater \u003cclg@fr.ibm.com\u003e\nSigned-off-by: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nAcked-by: Serge E.
