New features include:
- Add NFS client support for containers.
This should enable most of the necessary functionality, including
lockd support, and support for rpc.statd, NFSv4 idmapper and
RPCSEC_GSS upcalls into the correct network namespace from
which the mount system call was issued.
- NFSv4 idmapper scalability improvements
Base the idmapper cache on the keyring interface to allow concurrent
access to idmapper entries. Start the process of migrating users from
the single-threaded daemon-based approach to the multi-threaded
request-key based approach.
- NFSv4.1 implementation id.
Allows the NFSv4.1 client and server to mutually identify each other
for logging and debugging purposes.
- Support the 'vers=4.1' mount option for mounting NFSv4.1 instead of
having to use the more counterintuitive 'vers=4,minorversion=1'.
- SUNRPC tracepoints.
Start the process of adding tracepoints in order to improve debugging
of the RPC layer.
- pNFS object layout support for autologin.
Important bugfixes include:
- Fix a bug in rpc_wake_up/rpc_wake_up_status that caused them to fail
to wake up all tasks when applied to priority waitqueues.
- Ensure that we handle read delegations correctly, when we try to
truncate a file.
- A number of fixes for NFSv4 state manager loops (mostly to do with
delegation recovery).
