Merge tag 'nfs-for-4.4-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull NFS client updates from Trond Myklebust:
"Highlights include:
New features:
- RDMA client backchannel from Chuck
- Support for NFSv4.2 file CLONE using the btrfs ioctl
Bugfixes + cleanups:
- Move socket data receive out of the bottom halves and into a
workqueue
- Refactor NFSv4 error handling so synchronous and asynchronous RPC
handles errors identically.
- Fix a panic when blocks or object layouts reads return a bad data
length
- Fix nfsroot so it can handle a 1024 byte long path.
- Fix bad usage of page offset in bl_read_pagelist
- Various NFSv4 callback cleanups+fixes
- Fix GETATTR bitmap verification
- Support hexadecimal number for sunrpc debug sysctl files"
