  NFS: Fix RCU dereference of cl_xprt in nfs_compare_super_address (2026-04-22 08:53:23 -0400)

----------------------------------------------------------------
NFS client updates for Linux 7.1

Highlights include:

Bugfixes:
- NFS: Fix handling of ENOSPC so that if we have to resend writes, they
  are written synchronously.
- SUNRPC: RDMA transport fixes from Chuck
- NFSv4.2: Several fixes for delegated timestamps
- NFSv4: Failure to obtain a directory delegation should not cause
  stat() to fail.
- NFSv4: Rename was failing to update timestamps when a directory
  delegation is held.
- NFSv4: Ensure we check rsize/wsize after crossing a NFSv4 filesystem
  boundary.
- NFSv4/pnfs: If the server is down, retry the layout returns on reboot
- NFSv4/pnfs: Fallback to MDS could result in a short write being
  incorrectly logged.

Cleanups:
- NFS: use memcpy_and_pad in decode_fh
