commitf41ebe9defupstream. When a probe point is expanded to several places (like inlined) and if some of them are skipped because of blacklisted or __init function, those trace_events has no event name. It must be skipped while showing results. Without this fix, you can see "(null):(null)" on the list, # ./perf probe request_resource reserve_setup is out of .text, skip it. Added new events: (null):(null) (on request_resource) probe:request_resource (on request_resource) You can now use it in all perf tools, such as: perf record -e probe:request_resource -aR sleep 1 # With this fix, it is ignored: # ./perf probe request_resource reserve_setup is out of .text, skip it. Added new events: probe:request_resource (on request_resource) You can now use it in all perf tools, such as: perf record -e probe:request_resource -aR sleep 1 # Fixes:5a51fcd1f3("perf probe: Skip kernel symbols which is out of .text") Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: stable@vger.kernel.org Link: http://lore.kernel.org/lkml/158763968263.30755.12800484151476026340.stgit@devnote2 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
