Make it possible to create a new mount from a already working server. Here's a detailed description of the problem from Jakob: "The background for this question is occasional problems we see with our fuse filesystem [1] and mount namespaces. On a usual client, we have system-wide, autofs managed mountpoints. When a new mount namespace is created (which can be done unprivileged in combination with user namespaces), it can happen that a mountpoint is used inside the new namespace but idle in the root mount namespace. So autofs unmounts the parent, system-wide mountpoint. But the fuse module stays active and still serves mountpoint in the child mount namespace. Because the fuse daemon also blocks other system wide resources corresponding to the mountpoint, this situation effectively prevents new mounts until the child mount namespaces closes.

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.
