This patchset contains two 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.

Geliang Tang (2):
  bpf: verifier: Fix return value of fixup_call_args
  libbpf: handle ENOTSUPP in libbpf_strerror_r
