3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Kinglong Mee <kinglongmee@xxxxxxxxx> commit d9499a95716db0d4bc9b67e88fd162133e7d6b08 upstream. A memory allocation failure could cause nfsd_startup_generic to fail, in which case nfsd_users wouldn't be incorrectly left elevated. After nfsd restarts nfsd_startup_generic will then succeed without doing anything--the first consequence is likely nfs4_start_net finding a bad laundry_wq and crashing.
