NFS cache consistency updates:\n * Use the ctime to emulate a change attribute for NFSv2/v3 so that\n all NFS versions can share the same cache management code.\n * New cache management code will only look at the change attribute\n and size attribute when deciding whether or not our cached data\n is still valid or not.\n * Don\u0027t request NFSv4 post-op attributes on writes in cases such as\n O_DIRECT, where we don\u0027t care about data cache consistency, or\n when we have a write delegation, and know that our cache is still\n consistent.\n * Don\u0027t request NFSv4 post-op attributes on operations such as\n COMMIT, where there are no expected metadata updates.\n * Don\u0027t request NFSv4 directory post-op attributes in cases where\n the operations themselves already return change attribute\n updates: i.e. operations such as OPEN, CREATE, REMOVE, LINK and\n RENAME.\n -

Add NFS client support for containers.\n\n This should enable most of the necessary functionality, including\n lockd support, and support for rpc.statd, NFSv4 idmapper and\n RPCSEC_GSS upcalls into the correct network namespace from which\n the mount system call was issued.\n\n - NFSv4 idmapper scalability improvements\n\n Base the idmapper cache on the keyring interface to allow\n concurrent access to idmapper entries. Start the process of\n migrating users from the single-threaded daemon-based approach to\n the multi-threaded request-key based approach.\n\n - NFSv4.1 implementation id.\n\n Allows the NFSv4.1 client and server to mutually identify each\n other for logging and debugging purposes.\n\n - Support the \u0027vers\u003d4.1\u0027 mount option for mounting NFSv4.1 instead of\n having to use the more counterintuitive \u0027vers\u003d4,minorversion\u003d1\u0027.\n\n - SUNRPC tracepoints.\n\n Start the process of adding tracepoints in order to improve\n debugging of the RPC layer.\n\n - pNFS object layout support for autologin.\n\n Important bugfixes include:\n\n - Fix a bug in rpc_wake_up/rpc_wake_up_status that caused them to\n fail to wake up all tasks when applied to priority waitqueues.\n\n - Ensure that we handle read delegations correctly, when we try to\n truncate a file.\n\n - A number of fixes for NFSv4 state manager loops (mostly to do with\n delegation recovery).\"\n\n* tag
