rcu: Use call_rcu_func_t to replace explicit type equivalents (db3e8db4) · Commits · 戴 / test

We have had the call_rcu_func_t typedef for a quite awhile, but we still use explicit function pointer types in some places. These types can confuse cscope and can be hard to read. This patch therefore replaces these types with the call_rcu_func_t typedef. Signed-off-by:
