From 3fb87d13ce29637e0ae005fa66a4f917cce6fede Mon Sep 17 00:00:00 2001 From: Benny Halevy Date: Fri, 30 May 2014 09:09:31 -0400 Subject: nfsd4: hash deleg stateid only on successful nfs4_set_delegation We don't want the stateid to be found in the hash table before the delegation is granted. Currently this is protected by the client_mutex, but we want to break that up and this is a necessary step toward that goal. Signed-off-by: Benny Halevy Signed-off-by: J.
