Merge tag 'nfs-for-3.7-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull NFS client updates from Trond Myklebust:
"Features include:
- Remove CONFIG_EXPERIMENTAL dependency from NFSv4.1
Aside from the issues discussed at the LKS, distros are shipping
NFSv4.1 with all the trimmings.
- Fix fdatasync()/fsync() for the corner case of a server reboot.
- NFSv4 OPEN access fix: finally distinguish correctly between
open-for-read and open-for-execute permissions in all situations.
- Ensure that the TCP socket is closed when we're in CLOSE_WAIT
- More idmapper bugfixes
- Lots of pNFS bugfixes and cleanups to remove unnecessary state and
make the code easier to read.
- In cases where a pNFS read or write fails, allow the client to
resume trying layoutgets after two minutes of read/write-
through-mds.
- More net namespace fixes to the NFSv4 callback code.
- More net namespace fixes to the NFSv3 locking code.
- More NFSv4 migration preparatory patches.
Including patches to detect network trunking in both NFSv4 and
NFSv4.1
- pNFS block updates to optimise LAYOUTGET calls."
* tag 'nfs-for-3.7-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (113 commits)
pnfsblock: cleanup nfs4_blkdev_get
NFS41: send real read size in layoutget
NFS41: send real write size in layoutget
NFS: track direct IO left bytes
NFSv4.1: Cleanup ugliness in pnfs_layoutgets_blocked()
NFSv4.1: Ensure that the layout sequence id stays 'close' to the current
NFSv4.1: Deal with seqid wraparound in the pNFS return-on-close code
NFSv4 set open access operation call flag in nfs4_init_opendata_res
NFSv4.1: Remove the dependency on CONFIG_EXPERIMENTAL
NFSv4 reduce attribute requests for open reclaim
NFSv4: nfs4_open_done first must check that GETATTR decoded a file type
NFSv4.1: Deal with wraparound when updating the layout "barrier" seqid
NFSv4.1: Deal with wraparound issues when updating the layout stateid
NFSv4.1: Always set the layout stateid if this is the first layoutget
NFSv4.1: Fix another refcount issue in pnfs_find_alloc_layout
NFSv4: don't put ACCESS in OPEN compound if O_EXCL
NFSv4: don't check MAY_WRITE access bit in OPEN
NFS: Set key construction data for the legacy upcall
NFSv4.1: don't do two EXCHANGE_IDs on mount
NFS: nfs41_walk_client_list(): re-lock before iterating
