If a file may contain unstable writes that can error out, then we want to avoid garbage collecting the struct nfsd_file that may be tracking those errors. So in the garbage collector, we try to avoid collecting files that aren't clean. Furthermore, we avoid immediately kicking off the garbage collector in the case where the reference drops to zero for the case where there is a write error that is being tracked. If the file is unhashed while an error is pending, then declare a reboot, to ensure the client resends any unstable writes.

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.
