Subject: [PATCH v1 0/5] perf trace: Augment enum arguments with BTF

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, which makes more syscalls to 
be traceable by perf trace.

Test is included.
