Merge git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux

I pushed a version of the crypto iov_iter bug fix that
Al Viro wrote, but Linus put in a different copy of the
same fix into his tree.

I then reverted my commit in net-next, and that's why we have a merge
when pulling in Linus's tree.

Merge tag 'nfs-for-3.20-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

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"
