If the server returns NFS4ERR_OLD_STATEID in response to our delegreturn, we want to sync to the most recent seqid for the delegation stateid. However if we are already at the most recent, we have two possibilities: - an OPEN reply is still outstanding and will return a new seqid - an earlier OPEN reply was dropped on the floor due to a timeout. In the latter case, we may end up unable to complete the delegreturn, so we want to bump the seqid to a value greater than the cached value. While this may cause us to lose the delegation in the former case, it should now be safe to assume that the client will replay the OPEN if necessary in order to get a new valid stateid.

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.
