Subject: [RFC][PATCH 0/6] tracing: Fix bogus parsing of probes and set_ftrace_filter


Al Viro pointed out a couple of bugs with the parsing of the
removing of function probes and the parsing of set_ftrace_filter
strings.

This patch series implements his suggested fixes and adds selftests
that would have caught the bugs in the first place.


Steven Rostedt (VMware) (6):
      ftrace: Remove incorrect setting of glob search field
      tracing: Fix parsing of globs with a wildcard at the beginning
      selftests/ftrace: Have reset_ftrace_filter handle modules
      selftests/ftrace: Have reset_ftrace_filter handle multiple instances
      selftests/ftrace: Add some missing glob checks
      selftests/ftrace: Add more tests for removing of function probes
