Subject: [PATCH v2 0/2] pahole: Make encoding percpu vars into BTF optional.
Date: Mon, 21 Sep 2020 12:53:08 -0700
Message-ID: <20200921195310.3070085-1-haoluo@google.com> (raw)

v1 -> v2:
 - Use opt-out instead of opt-in. Rename the flag name to
   '--skip_encoding_btf_vars'

Previous commit f3d9054ba8ff ("btf_encoder: Teach pahole to store
percpu variables in vmlinux BTF.") introduced a feature in btf_encoder
that encodes global symbols in BTF. However, this feature is not
protected by any flag. In order to avoid surprises after Pahole v1.18
rolls out, add a flag to toggle this feature off.

Also as a refactor, introduce '--btf_encode_force' to replace the
old '--force' and '-j' option that is used to forcefully emit BTF.

Hao Luo (2):
  btf_encoder: Allow disabling BTF var encoding.
  btf_encoder: Introduce option '--btf_encode_force'
