For '*foo' pattern, we should allow any string ending with 'foo', but ftrace filter incorrectly disallows strings like bar_foo_foo: # echo '*io' > set_ftrace_filter # cat set_ftrace_filter | grep 'req_bio_endio' # cat available_filter_functions | grep 'req_bio_endio' req_bio_endio Signed-off-by: Li Zefan <lizf@cn.fujitsu.com> LKML-Reference: <4B4E870E.6060607@cn.fujitsu.com> Acked-by: Frederic Weisbecker <fweisbec@gmail.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
