Subject: [PATCH v3 00/28] selftests/ftrace: Improve ftracetest with coverage check

Hi,

Here is the 3rd version of the series for improving ftracetest
testcase using gcov/lcov. In this version I just fixed some
reported issues and dropped some tests which is not needed.
I also dropped a testcase for blktrace from this version.
It will be discussed separated thread.

Previous version is here;

https://lkml.org/lkml/2018/8/16/393

GCOV_PROFILE_FTRACE has already been merged through tracing
tree.

Ftracetest framework improvements:
 - Add --stop-fail for detecting failure soon.
 - Add --console for interactively debugging a testcase by shell.
 - Add testcase-number prefix to logfile for finding log easier.
 - Improve general init function
 - Add SPDX license identifiers
 - Call general init function after all testcases.
 - Remove init/cleanup code from all testcase (since general init
   function will fixed it up)

Testcase fixes:
 - Fix to check $comm availability.
 - Make checkbashisms clean

Testcase improvements:
 - Use loopback address instead of localhost
 - Improve kprobe on module testcase to load/unload module
 - Improve kprobe testcase to check log data
 - Improve kretprobe testcase to check log data
 - Test kprobe-event argument with various bitsize
 - Check set_event_pid result

Adding testcases:
 - Add kprobe event with $comm argument testcase
 - Add kprobe profile testcase
 - Add kprobe-event with symbol argument testcase
 - Add trace_printk sample module testcase
 - Add ringbuffer size changing testcase
 - Add function profiling statistics testcase
 - Add max stack tracer testcase
 - Add function filter on module testcase
 - Add trace_pipe testcase
 - Add stacktrace ftrace filter command testcase
 - Add wakeup tracer testcase
 - Add wakeup_rt tracer testcase
 - Add ftrace cpumask testcase

TBD:
Following testcase improvements are remaining.
 - Checking of various supported types (like u8, u64 etc.)
   testcases

Tested on x86-64 qemu.

# of passed:  84
# of failed:  0
# of unresolved:  0
# of untested:  0
# of unsupported:  0
# of xfailed:  0
# of undefined(test bug):  0

Thank you,
