Note that there is a conflict with the rdma tree in this pull request, since
we delete a file that has been changed in the rdma tree. Hopefully that's
easy enough to resolve!
We also were unable to track down a maintainer for Neil Brown's changes to
the generic cred code that are prerequisites to his RPC cred cleanup patches.
We've been asking around for several months without any response, so
hopefully it's okay to include those patches in this pull request.
Stable bugfixes:
- xprtrdma: Yet another double DMA-unmap # v4.20
Features:
- Allow some /proc/sys/sunrpc entries without CONFIG_SUNRPC_DEBUG
- Per-xprt rdma receive workqueues
- Drop support for FMR memory registration
- Make port= mount option optional for RDMA mounts
Other bugfixes and cleanups:
- Remove unused nfs4_xdev_fs_type declaration
- Fix comments for behavior that has changed
- Remove generic RPC credentials by switching to 'struct cred'
- Fix crossing mountpoints with different auth flavors
- Various xprtrdma fixes from testing and auditing the close code
- Fixes for disconnect issues when using xprtrdma with krb5
- Clean up and improve xprtrdma trace points
- Fix NFS v4.2 async copy reboot recovery
