  nfsd: allow for up to 32 callback session slots (2024-11-18 20:23:13 -0500)

----------------------------------------------------------------
NFSD 6.13 Release Notes

Jeff Layton contributed a scalability improvement to NFSD's NFSv4
backchannel session implementation. This improvement is intended to
increase the rate at which NFSD can safely recall NFSv4 delegations
from clients, to avoid the need to revoke them. Revoking requires
a slow state recovery process.

A wide variety of bug fixes and other incremental improvements make
up the bulk of commits in this series. As always I am grateful to
the NFSD contributors, reviewers, testers, and bug reporters who
participated during this cycle.
