Merge branch 'for-3.17' of git://linux-nfs.org/~bfields/linux
Pull nfsd updates from Bruce Fields: "This includes a major rewrite of the NFSv4 state code, which has always depended on a single mutex. As an example, open creates are no longer serialized, fixing a performance regression on NFSv3->NFSv4 upgrades. Thanks to Jeff, Trond, and Benny, and to Christoph for review. Also some RDMA fixes from Chuck Lever and Steve Wise, and miscellaneous fixes from Kinglong Mee and others" * 'for-3.17' of git://linux-nfs.org/~bfields/linux: (167 commits) svcrdma: remove rdma_create_qp() failure recovery logic nfsd: add some comments to the nfsd4 object definitions nfsd: remove the client_mutex and the nfs4_lock/unlock_state wrappers nfsd: remove nfs4_lock_state: nfs4_state_shutdown_net nfsd: remove nfs4_lock_state: nfs4_laundromat nfsd: Remove nfs4_lock_state(): reclaim_complete() nfsd: Remove nfs4_lock_state(): setclientid, setclientid_confirm, renew nfsd: Remove nfs4_lock_state(): exchange_id, create/destroy_session() nfsd: Remove nfs4_lock_state(): nfsd4_open and nfsd4_open_confirm nfsd: Remove nfs4_lock_state(): nfsd4_delegreturn() nfsd: Remove nfs4_lock_state(): nfsd4_open_downgrade + nfsd4_close nfsd: Remove nfs4_lock_state(): nfsd4_lock/locku/lockt() nfsd: Remove nfs4_lock_state(): nfsd4_release_lockowner nfsd: Remove nfs4_lock_state(): nfsd4_test_stateid/nfsd4_free_stateid nfsd: Remove nfs4_lock_state(): nfs4_preprocess_stateid_op() nfsd: remove old fault injection infrastructure nfsd: add more granular locking to *_delegations fault injectors nfsd: add more granular locking to forget_openowners fault injector nfsd: add more granular locking to forget_locks fault injector nfsd: add a list_head arg to nfsd_foreach_client_lock ...
