Hi Linus-

NFSD pull request follows below. First some notes:

Stephen Rothwell reports a minor merge conflict with Jeff Layton's
file-locks tree (and now your tree):

https://lore.kernel.org/lkml/20210824100737.4bd6d815@canb.auug.org.au/

The resolution Stephen provided should be adequate.


There are two v5.13 regressions we are aware of:

- "[Bug 213887] kernel v5.13 regression & NFSv4.2 client timeouts?"

  This issue appears to be addressed by recent commit 062b829c52ef
  ("SUNRPC: Fix XPT_BUSY flag leakage in svc_handle_xprt()...")

- NFS server regression in kernel 5.13 (tested w/ 5.13.9)

  A fix for this has been queued for nfsd-5.15-1. It was a bit late
  to be included in nfsd-5.15.


And there are two longstanding issues we are aware of:

- BTRFS subvolumes cannot be exported properly by NFSD

  As featured on lwn.net:

  Part I:  https://lwn.net/Articles/866582/
  Part II: https://lwn.net/Articles/866709/

  Neil Brown is working on a set of patches to address this.

- NFSv4.1+ backchannel not getting restored after PATH_DOWN

  This might be an NFS/RDMA-only problem. The reproducer is very
  rare, so it's taking a while to nail down.
