Merge tag 'nfs-for-5.1-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull NFS client updates from Trond Myklebust:
"Highlights include:
Stable fixes:
- Fixes for NFS I/O request leakages
- Fix error handling paths in the NFS I/O recoalescing code
- Reinitialise NFSv4.1 sequence results before retransmitting a
request
- Fix a soft lockup in the delegation recovery code
- Bulk destroy of layouts needs to be safe w.r.t. umount
- Prevent thundering herd issues when the SUNRPC socket is not
connected
- Respect RPC call timeouts when retrying transmission
Features:
- Convert rpc auth layer to use xdr_streams
- Config option to disable insecure RPCSEC_GSS crypto types
- Reduce size of RPC receive buffers
- Readdirplus optimization by cache mechanism
- Convert SUNRPC socket send code to use iov_iter()
- SUNRPC micro-optimisations to avoid indirect calls
- Add support for the pNFS LAYOUTERROR operation and use it with the
pNFS/flexfiles driver
- Add trace events to report non-zero NFS status codes
- Various removals of unnecessary dprintks
Bugfixes and cleanups:
- Fix a number of sparse warnings and documentation format warnings
- Fix nfs_parse_devname to not modify it's argument
- Fix potential corruption of page being written through pNFS/blocks
- fix xfstest generic/099 failures on nfsv3
- Avoid NFSv4.1 "false retries" when RPC calls are interrupted
- Abort I/O early if the pNFS/flexfiles layout segment was
invalidated
- Avoid unnecessary pNFS/flexfiles layout invalidations"
