From: Geliang Tang <tanggeliang@xxxxxxxxxx> v2: - patch 1, only commit log updated - update patch 2 - add an unsigned variable - use "switch-case" - only "Operation not supported", no (-524) in string - patch 3, a now one This patchset contains three fixes for handling errno ENOTSUPP. Patch 1 fixes the return value of fixup_call_args() to make sure ENOTSUPP is returned to user space correctly. Patch 2 handles ENOTSUPP in libbpf_strerror_r() in libbpf. Patch 3 includes str_error.h in BPF selftests, and drop duplicate ENOTSUPP definitions.
