[PATCH v3 0/2] btrfs-progs: tests: Enahance INSTRUMENT coverage

[Qu Wenruo <wqu@suse.com>]

This patchset will enhance INSTRUMENT coverage for all btrfs related
commands.

Since now INSTRUMENT would also cover a lot of btrfs inspect-dump
comands, fix some test cases where INSTRUMENT output could easily
pollute them.


Now fsck/convert/misc/mkfs all pass with
INSTRUMENT="valgrind --leak-check=full".

Changelog:
v2:
- Pass INSTRUMENT as space split command

- Unset previous cmmd_array in expand_command()
  Instead of unsetting it.

- Use local variable @i in expand_command()
  To fix misc/004

- Add extra commands for INSTRUMENT coverage
  This incldues btrfstune, btrfs-corrupt-block, btrfs-image,
  btrfs-select-super, btrfs-find-root.

- Fix test cases which uses run_check_stdout without filtering

v3:
- Adding proper filtering for run_check_stdout() callers
  Instead of removing run_check_stdout(), to keep the coverage the same.

Qu Wenruo (2):
  btrfs-progs: tests: Filter output for run_check_stdout
  btrfs-progs: tests: Introduce expand_command() to inject aruguments
    more accurately
