Instead of using kernel\nthreads for stop_machine we now use a an rt workqueue to synchronize all\ncpus.\nThis has the advantage that all needed per cpu threads are already created\nwhen stop_machine gets called. And therefore a call to stop_machine won\u0027t\nfail anymore. This is needed for s390 which needs a mechanism to synchronize\nall cpus without allocating any memory.\nAs Rusty pointed out free_module() needs a non-failing stop_machine interface\nas well.\n\nAs a side effect the stop_machine code gets simplified.\n\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n" }, { "commit": "0d557dc97f4bb501f086a03d0f00b99a7855d794", "tree": "be717fc70de4fc76f48cf4f4f3cebc3b8569d798", "parents": [ "a802dd0eb5fc97a50cf1abb1f788a8f6cc5db635" ], "author": { "name": "Heiko Carstens", "email": "heiko.carstens@de.ibm.com", "time": "Mon Oct 13 23:50:09 2008 +0200" }, "committer": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Wed Oct 22 10:00:25 2008 +1100" }, "message": "workqueue: introduce create_rt_workqueue\n\ncreate_rt_workqueue will create a real time prioritized workqueue.\nThis is needed for the conversion of stop_machine to a workqueue based\nimplementation.\nThis patch adds yet another parameter to __create_workqueue_key to tell\nit that we want an rt workqueue.\nHowever it looks like we rather should have something like \"int type\"\ninstead of singlethread, freezable and rt.\n\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "f44dd164f37336f7e17fabf5740698fd10635172", "tree": "13af05d200a37e5936beaaf0edfd4c58d405fb1e", "parents": [ "d0ea3d7d286aeda2a9216d76424abc285b87b7b4" ], "author": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Wed Oct 22 10:00:24 2008 -0500" }, "committer": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Wed Oct 22 10:00:25 2008 +1100" }, "message": "Make panic\u003d and panic_on_oops into core_params\n\nThis allows them to be examined and set after boot, plus means they\nactually give errors if they are misused (eg. panic\u003dyes).\n\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n" }, { "commit": "67e67ceaac5bf55dbdceb704ff2d763d438b5373", "tree": "59523536661c93dce7a02557ca6ac5827a7bf75f", "parents": [ "9b473de87209fa86eb421b23386693b461612f30" ], "author": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Wed Oct 22 10:00:23 2008 -0500" }, "committer": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Wed Oct 22 10:00:23 2008 +1100" }, "message": "core_param() for genuinely core kernel parameters\n\nThere are a lot of one-liner uses of __setup() in the kernel: they\u0027re\ncumbersome and not queryable (definitely not settable) via /sys.

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.
