Merge tag 'nfs-for-3.11-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull NFS client updates from Trond Myklebust: "Feature highlights include: - Add basic client support for NFSv4.2 - Add basic client support for Labeled NFS (selinux for NFSv4.2) - Fix the use of credentials in NFSv4.1 stateful operations, and add support for NFSv4.1 state protection. Bugfix highlights: - Fix another NFSv4 open state recovery race - Fix an NFSv4.1 back channel session regression - Various rpc_pipefs races - Fix another issue with NFSv3 auth negotiation Please note that Labeled NFS does require some additional support from the security subsystem. The relevant changesets have all been reviewed and acked by James Morris." * tag 'nfs-for-3.11-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (54 commits) NFS: Set NFS_CS_MIGRATION for NFSv4 mounts NFSv4.1 Refactor nfs4_init_session and nfs4_init_channel_attrs nfs: have NFSv3 try server-specified auth flavors in turn nfs: have nfs_mount fake up a auth_flavs list when the server didn't provide it nfs: move server_authlist into nfs_try_mount_request nfs: refactor "need_mount" code out of nfs_try_mount SUNRPC: PipeFS MOUNT notification optimization for dying clients SUNRPC: split client creation routine into setup and registration SUNRPC: fix races on PipeFS UMOUNT notifications SUNRPC: fix races on PipeFS MOUNT notifications NFSv4.1 use pnfs_device maxcount for the objectlayout gdia_maxcount NFSv4.1 use pnfs_device maxcount for the blocklayout gdia_maxcount NFSv4.1 Fix gdia_maxcount calculation to fit in ca_maxresponsesize NFS: Improve legacy idmapping fallback NFSv4.1 end back channel session draining NFS: Apply v4.1 capabilities to v4.2 NFSv4.1: Clean up layout segment comparison helper names NFSv4.1: layout segment comparison helpers should take 'const' parameters NFSv4: Move the DNS resolver into the NFSv4 module rpc_pipefs: only set rpc_dentry_ops if d_op isn't already set ...
