From 84a80f62f71beac20a426709c04b49f2bd352291 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 9 Mar 2015 15:23:35 -0400 Subject: NFSv4.1: Convert pNFS deviceid to use kfree_rcu() Use of synchronize_rcu() when unmounting and potentially freeing a lot of deviceids is problematic. There really is no reason why we can't just use kfree_rcu() here.
