  "message": "ftrace: add filter select functions to trace\n\nThis patch adds two files to the debugfs system:\n\n /debugfs/tracing/available_filter_functions\n\nand\n\n /debugfs/tracing/set_ftrace_filter\n\nThe available_filter_functions lists all functions that has been\nrecorded by the ftraced that has called the ftrace_record_ip function.\nThis is to allow users to see what functions have been converted\nto nops and can be enabled for tracing.\n\nTo enable functions, simply echo the names (whitespace delimited)\ninto set_ftrace_filter. Simple wildcards are also allowed.\n\necho \u0027scheduler\u0027 \u003e /debugfs/tracing/set_ftrace_filter\n\nWill have only the scheduler be activated when tracing is enabled.\n\necho \u0027sched_*\u0027 \u003e /debugfs/tracing/set_ftrace_filter\n\nWill have only the functions starting with \u0027sched_\u0027 be activated.\n\necho \u0027*lock\u0027 \u003e /debugfs/tracing/set_ftrace_filter\n\nWill have only functions ending with \u0027lock\u0027 be activated.\n\necho \u0027*lock*\u0027 \u003e /debugfs/tracing/set_ftrace_filter\n\nWill have only functions with \u0027lock\u0027 in its name be activated.\n\nNote: \u0027sched*lock\u0027 will not work. The only wildcards that are\nallowed is an asterisk and the beginning and or end of the string\npassed in.\n\nMultiple names can be passed in with whitespace delimited:\n\necho \u0027scheduler *lock *acpi*\u0027 \u003e /debugfs/tracing/set_ftrace_filter\n\nis also the same as:\n\necho \u0027scheduler\u0027 \u003e /debugfs/tracing/set_ftrace_filter\necho \u0027*lock\u0027 \u003e\u003e /debugfs/tracing/set_ftrace_filter\necho \u0027*acpi*\u0027 \u003e\u003e /debugfs/tracing/set_ftrace_filter\n\nAppending does just that. It appends to the list.\n\nTo disable all filters simply echo an empty line in:\n\necho \u003e /debugfs/tracing/set_ftrace_filter\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n",
