[ Upstream commit 87c259a7a359e73e6c52c68fcbec79988999b4e6 ] When adding folio_memcg function call in the zram module for Android16-6.12, the following error occurs during compilation: ERROR: modpost: "cgroup_mutex" [../soc-repo/zram.ko] undefined! This error is caused by the indirect call to lockdep_is_held(&cgroup_mutex) within folio_memcg. The export setting for cgroup_mutex is controlled by the CONFIG_PROVE_RCU macro. If CONFIG_LOCKDEP is enabled while CONFIG_PROVE_RCU is not, this compilation error will occur. To resolve this issue, add a parallel macro CONFIG_LOCKDEP control to ensure cgroup_mutex is properly exported when needed.
