POSIX typically only refreshes the user's supplementary group information upon login. Since NFS servers may often refresh their concept of the user supplementary group membership at their own cadence, it is possible for the NFS client's access cache to become stale due to the user's group membership changing on the server after the user has already logged in on the client. While it is reasonable to expect that such group membership changes are rare, and that we do not want to optimise the cache to accommodate them, it is also not unreasonable for the user to expect that if they log out and log back in again, that the staleness would clear up.

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.
