pNFS/flexfiles: Always attempt to call layoutstats when flexfiles is enabled (2017-05-09 16:02:57 -0400)

----------------------------------------------------------------
NFS client updates for Linux 4.12

Highlights include:

Stable bugfixes:
- Fix use after free in write error path
- Use GFP_NOIO for two allocations in writeback
- Fix a hang in OPEN related to server reboot
- Check the result of nfs4_pnfs_ds_connect
- Fix an rcu lock leak

Features:
- Removal of the unmaintained and unused OSD pNFS layout
- Cleanup and removal of lots of unnecessary dprintk()s
- Cleanup and removal of some memory failure paths now that
GFP_NOFS is guaranteed to never fail.
- Remove the v3-only data server limitation on pNFS/flexfiles

Bugfixes:
- RPC/RDMA connection handling bugfixes
- Copy offload: fixes to ensure the copied data is COMMITed to disk.
- Readdir: switch back to using the ->iterate VFS interface
- File locking fixes from Ben Coddington
- Various use-after-free and deadlock issues in pNFS
- Write path bugfixes
