Pull NFS client updates from Trond Myklebust:
"Highlights incluse:
Features:
- Removing the forced serialisation of open()/close() calls in
NFSv4.x (x>0) makes for a significant performance improvement in
metadata intensive workloads.
- Full support for the pNFS "flexible files" layout type
- Further RPC/RDMA client improvements from Chuck
Bugfixes:
- Stable fix: NFSv4.1 backchannel calls blocking operations with !TASK_RUNNING
- Stable fix: pnfs_generic_pg_init_read/write can be called with lseg == NULL
- Stable fix: Fix an Oopsable condition when nsm_mon_unmon is called
as part of the namespace cleanup,
- Stable fix: Ensure we reference the inode for return-on-close in
delegreturn
- Use SO_REUSEPORT to ensure that NFSv3 TCP connections can rebind to
the same source address/port combination during a disconnect/
reconnect event. This is a requirement imposed by most NFSv3
server duplicate reply cache implementations.
Optimisations:
- Ask for no NFSv4.1 delegations on OPEN if using O_DIRECT
Other:
- Add Anna Schumaker as co-maintainer for the NFS client"
