Subject: [PATCH bpf-next] bpf/local_storage: Fix build without CONFIG_CGROUP
Date: Fri, 24 Jul 2020 16:17:53 -0500	[thread overview]
Message-ID: <20200724211753.902969-1-zhuyifei1999@gmail.com> (raw)

From: YiFei Zhu <zhuyifei@google.com>

local_storage.o has its compile guard as CONFIG_BPF_SYSCALL, which
does not imply that CONFIG_CGROUP is on. Including cgroup-internal.h
when CONFIG_CGROUP is off cause a compilation failure.

Reported-by: kernel test robot <lkp@intel.com>
Fixes: f67cfc233706 ("bpf: Make cgroup storages shared between programs on the same cgroup")
