__fh_verify() offers an interface like fh_verify() but doesn't require a struct svc_rqst *, instead it also takes the specific parts as explicit required arguments. So it is safe to call __fh_verify() with a NULL rqstp, but the net, cred, and client args must not be NULL. __fh_verify() does not use SVC_NET(), nor does the functions it calls. Rather than using rqstp->rq_client pass the client and gssclient explicitly to __fh_verify and then to nfsd_set_fh_dentry(). Lastly, it should be noted that the previous commit prepared for 4 associated tracepoints to only be used if rqstp is not NULL (this is a stop-gap that should be properly fixed so localio also benefits from the utility these tracepoints provide when debugging fh_verify issues).

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 reStructuredText 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.
