its\ndefault size (from its minimum size) but it will not expand the\nmax ring buffer (the ring buffer to store maximum latencies).\nWhen the irqsoff test runs, it will call the ring buffer swap routine\nthat checks if the max ring buffer is the same size as the normal\nring buffer, and will fail if it is not. This causes the test to fail.\n\nThe solution is to expand the max ring buffer before running the self\ntest if the max ring buffer is used by that tracer and the normal ring\nbuffer is expanded. The max ring buffer should be shrunk again after\nthe test is done to save space.\n\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n" }, { "commit": "9a24470b2826e4665b1484836c7ae6aba1ddea32", "tree": "277786327395bf98050498f0c97807f41dc8be45", "parents": [ "56355b83e2a24ce7e1870c8479205e2cdd332225" ], "author": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Wed Mar 09 14:53:38 2011 -0500" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Thu Mar 10 10:34:54 2011 -0500" }, "message": "tracing: Align 4 byte ints together in struct tracer\n\nMove elements in struct tracer for better alignment.\n\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n" }, { "commit": "56355b83e2a24ce7e1870c8479205e2cdd332225", "tree": "e85804c55de4f125332d8052c9181d2b8ae84a20", "parents": [ "31274d72f01604f4b02d933b4f3cac84d2c201fd" ], "author": { "name": "Yuanhan Liu", "email": "yuanhan.liu@linux.intel.com", "time": "Mon Nov 08 14:05:12 2010 +0800" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Thu Mar 10 10:34:51 2011 -0500" }, "message": "tracing: Export trace_set_clr_event()\n\nTrace events belonging to a module only exists when the module is\nloaded.

the tasks.\nAll running tasks have this stack created, as well as any new\ntasks.\n\nOn CPU hot plug, the new idle task will allocate a stack as well\nwhen init_idle() is called. The problem is that cpu hotplug does\nnot create a new idle_task. Instead it uses the idle task that\nexisted when the cpu went down.\n\nftrace_graph_init_task() will add a new ret_stack to the task\nthat is given to it. Because a clone will make the task\nhave a stack of its parent it does not check if the task\u0027s\nret_stack is already NULL or not. When the CPU hotplug code\nstarts a CPU up again, it will allocate a new stack even\nthough one already existed for it.\n\nThe solution is to treat the idle_task specially. In fact, the\nfunction_graph code already does, just not at init_idle().\nInstead of using the ftrace_graph_init_task() for the idle task,\nwhich that function expects the task to be a clone, have a\nseparate ftrace_graph_init_idle_task(). Also, we will create a\nper_cpu ret_stack that is used by the idle task. When we call\nftrace_graph_init_idle_task() it will check if the idle task\u0027s\nret_stack is NULL, if it is, then it will assign it the per_cpu\nret_stack.\n\nReported-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSuggested-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Stable Tree \u003cstable@kernel.org\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n" }, { "commit": "aceb91cd351bc3a19a783c901fe8a8070d5f6fa9", "tree": "a0863e940a77ae10d3c8b391488e29a8245b31be", "parents": [ "ae8eed2d0906bf0d8eb0c2a4651676a41d361297", "b8cf0e0e552ca48e9a00f518aeb4f5e03984022b" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Feb 09 11:45:21 2011 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Feb 09 11:45:21 2011 -0800" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.dk/linux-2.6-block\n\n* \u0027for-linus\u0027 of git://git.kernel.dk/linux-2.6-block:\n cdrom: support devices that have check_events but not media_changed\n cfq-iosched: Don\u0027t wait if queue already has requests.\n blkio-throttle: Avoid calling blkiocg_lookup_group() for root group\n cfq: rename a function to give it more appropriate name\n cciss: make cciss_revalidate not loop through CISS_MAX_LUNS volumes unnecessarily.\n drivers/block/aoe/Makefile: replace the use of \u003cmodule\u003e-objs with \u003cmodule\u003e-y\n loop: queue_lock NULL pointer derefence in blk_throtl_exit\n drivers/block/Makefile: replace the use of \u003cmodule\u003e-objs with \u003cmodule\u003e-y\n blktrace: Don\u0027t output messages if NOTIFY isn\u0027t set.\n" }, { "commit": "6752ab4a9c30d5411b2dfdb251a3f1cb18aae487", "tree": "2f6e2bb5b562c43b3b3d7efe095e196a19995395", "parents": [ "87d80de2800d087ea833cb79bc13f85ff34ed49f" ], "author": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Tue Feb 08 13:54:06 2011 -0500" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Tue Feb 08 17:14:58 2011 -0500" }, "message": "tracing: Deprecate tracing_enabled for tracing_on\n\ntracing_enabled should not be used, it is heavy weight and does not\ndo much in helping lower the overhead.\n\ntracing_on should be used instead.
