Subject: [PATCH v4 0/2] perf trace: Add more tests for BTF-augmented perf trace

Changes in v4:
 - Use if -f to check the existence of vmlinux BTF, and exit if it
   doesn't, so trace_test_string will not overwrite $err, and keep
   running the test.

Changes in v3:
 - Add vmlinux BTF check, and skip the tests if it doesn't exist

v1, v2:

The previous version of the perf trace BTF general augmentation tests
didn't pass Shellcheck (thanks to Arnaldo Carvalho de Melo
<acme@...nel.org> for pointing this out), this version uses bash instead
of POSIX shell to pass Shellcheck.

This patch series also adds documentation for the new option
--force-btf, which is used in the tests.
