From 75de874f5c35f679c6370fccc2bf4930e638ef3b Mon Sep 17 00:00:00 2001 From: Jesper Dangaard Brouer Date: Fri, 26 Jun 2009 10:45:58 +0000 Subject: sunrpc: Use rcu_barrier() on unload. The sunrpc module uses rcu_call() thus it should use rcu_barrier() on module unload. Have not verified that the possibility for new call_rcu() callbacks has been disabled. As a hint for checking, the functions calling call_rcu() (unx_destroy_cred and generic_destroy_cred) are registered as crdestroy function pointer in struct rpc_credops. Acked-by: Paul E.
