mm/list_lru.c: Rename kvfree_rcu() to local variant (e0feed08) · Commits · 戴 / test

Rename kvfree_rcu() function to the kvfree_rcu_local() one. The purpose is to prevent a conflict of two same function declarations. The kvfree_rcu() will be globally visible what would lead to a build error. No functional change.
