From: Chuck Lever <chuck.lever@oracle.com>

This series backports several upstream fixes to origin/linux-6.6.y
in order to address CVE-2024-46701:

  https://nvd.nist.gov/vuln/detail/CVE-2024-46701

As applied to origin/linux-6.6.y, this series passes fstests and the
git regression suite.

Before officially requesting that stable@ merge this series, I'd
like to provide an opportunity for community review of the backport
patches.

You can also find them them in the "nfsd-6.6.y" branch in

  https://git.kernel.org/pub/scm/linux/kernel/git/cel/linux.git
