Please pull nfsd changes for 3.16 from
git://linux-nfs.org/~bfields/linux.git for-3.16
The largest piece is a long-overdue rewrite of the xdr code to remove
some annoying limitations: for example, there was no way to return ACLs
larger than 4K, and readdir results were returned only in 4k chunks,
limiting performance on large directories.
Also:
- part of Neil Brown's work to make NFS work reliably over the
loopback interface (so client and server can run on the same
machine without deadlocks). The rest of it is coming through
other trees.
- cleanup and bugfixes for some of the server RDMA code, from
Steve Wise.
- Various cleanup of NFSv4 state code in preparation for an
overhaul of the locking, from Jeff, Trond, and Benny.
- smaller bugfixes and cleanup from Christoph Hellwig and
Kinglong Mee.
Thanks to everyone!
This summer looks likely to be busier than usual for knfsd. Hopefully
we won't break it too badly; testing definitely welcomed.
