[PATCH v2 0/5] perf trace: Augment enum arguments with BTF

[Howard Chu <howardchu95@gmail.com>]

changes in v2:
- Move inline landlock_add_rule c code to tests/workloads
- Rename 'enum_aug_prereq' to 'check_vmlinux'

Augment enum arguments in perf trace, including syscall arguments and
non-syscall tracepoint arguments. The augmentation is implemented using
BTF.

This patch series also includes a bug fix by Arnaldo Carvalho de Melo 
<acme@redhat.com>, which makes more syscalls to be traceable by perf trace.

Test is included.

  perf trace: Augment enum syscall arguments with BTF
  perf trace: Augment enum tracepoint arguments with BTF
  perf trace: Filter enum arguments with enum names
