This causes a problem with the\nfunction_graph tracer because it consumes the iteration in order to\ndetermine leaf functions.\n\nWhat happens is that the iterator stores the entry, and the function\ngraph plugin will look at the next entry. If that next entry is a return\nof the same function and task, then the function is a leaf and the\nfunction_graph plugin calls ring_buffer_read which moves the ring buffer\niterator forward (the trace iterator still points to the function start\nentry).\n\nThe copying of the trace_seq to the seq_file buffer will fail if the\nseq_file buffer is full. The seq_read will not show this entry.\nThe next read by userspace will cause seq_read to again call s_start\nwhich will reuse the trace iterator entry (the function start entry).\nBut the function return entry was already consumed. The function graph\nplugin will think that this entry is a nested function and not a leaf.\n\nTo solve this, the trace code now checks the return status of the\nseq_printf (trace_print_seq). If the writing to the seq_file buffer\nfails, we set a flag in the iterator (leftover) and we do not reset\nthe trace_seq buffer. On the next call to s_start, we check the leftover\nflag, and if it is set, we just reuse the trace_seq buffer and do not\ncall into the plugin print functions.\n\nBefore this patch:\n\n 2) | fput() {\n 2) | __fput() {\n 2) 0.550 us | inotify_inode_queue_event();\n 2) | __fsnotify_parent() {\n 2) 0.540 us | inotify_dentry_parent_queue_event();\n\nAfter the patch:\n\n 2) | fput() {\n 2) | __fput() {\n 2) 0.550 us | inotify_inode_queue_event();\n 2) 0.548 us | __fsnotify_parent();\n 2) 0.540 us | inotify_dentry_parent_queue_event();\n\n[\n Updated the patch to fix a missing return 0 from the trace_print_seq()\n stub when CONFIG_TRACING is disabled.\n\n Reported-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n]\n\nReported-by: Jiri Olsa \u003cjolsa@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n" }, { "commit": "29bf4a5e3fed3dde3eb629a0cb1762c1e9217458", "tree": "42a93ba9e1e7d0fb7b1f46382dba9a5245768629", "parents": [ "c521efd1700a8c0f7ce26f011f5eaecca17fabfa" ], "author": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Wed Dec 09 12:37:43 2009 -0500" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Wed Dec 09 12:47:35 2009 -0500" }, "message": "tracing: Only call pipe_close if pipe_close is defined\n\nThis fixes a cut and paste error that had pipe_close get called\nif pipe_open was defined (not pipe_close).\n\nReported-by: Kosaki Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nLKML-Reference: \u003c20091209153204.F4CD.A69D9226@jp.fujitsu.com\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n" }, { "commit": "822a6961112f0c9101d3359d8524604c3309ee6c", "tree": "ba66dda1220c6f3f9208b56cb50f716bbf08fa13", "parents": [ "ec89a06fd4e12301f11ab039ee07d2353a18addc" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Tue Dec 08 10:00:04 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Dec 09 10:32:21 2009 +0100" }, "message": "tracing/kprobes: Fix field creation\u0027s bad error handling\n\nWhen we define the common event fields in kprobe, we invert the error\nhandling and return immediately in case of success.
