rcu: Refactor kvfree_call_rcu() and high-level helpers
Currently a kvfree_call_rcu() takes an offset within a structure as a second parameter, so a helper such as a kvfree_rcu_arg_2() has to convert rcu_head and a freed ptr to an offset in order to pass it. That leads to an extra conversion on macro entry. Instead of converting, refactor the code in way that a pointer that has to be freed is passed directly to the kvfree_call_rcu(). This patch does not make any functional change and is transparent to all kvfree_rcu() users. Signed-off-by: Uladzislau Rezki (Sony) <urezki@gmail.com> Signed-off-by: Paul E.
