[ Upstream commit 68c522afd0b1936b48a03a4c8b81261e7597c62d ] nfsd_rename() can kick off a CB_RECALL (via vfs_rename() -> leases_conflict()) if a delegation is present. Before returning NFS4ERR_DELAY, give the client holding that delegation a chance to return it and then retry the nfsd_rename() again, once. This version of the patch handles renaming an existing file, but does not deal with renaming onto an existing file. That case will still always trigger an NFS4ERR_DELAY.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
