ftrace: add module command function filter selection
This patch adds a "command" syntax to the function filtering files: /debugfs/tracing/set_ftrace_filter /debugfs/tracing/set_ftrace_notrace Of the format: <function>:<command>:<parameter> The command is optional, and dependent on the command, so are the parameters. echo do_fork > set_ftrace_filter Will only trace 'do_fork'. echo 'sched_*' > set_ftrace_filter Will only trace functions starting with the letters 'sched_'. echo '*:mod:ext3' > set_ftrace_filter Will trace only the ext3 module functions. echo '*write*:mod:ext3' > set_ftrace_notrace Will prevent the ext3 functions with the letters 'write' in the name from being traced. echo '!*_allocate:mod:ext3' > set_ftrace_filter Will remove the functions in ext3 that end with the letters '_allocate' from the ftrace filter. Although this patch implements the 'command' format, only the 'mod' command is supported. More commands to follow. Signed-off-by: Steven Rostedt <srostedt@redhat.com>
