|
|
With FUSE it is possible to implement a fully functional filesystem
|
|
in a userspace program.
|
|
|
|
There's also a companion library: libfuse2. This library is available
|
|
from the FUSE homepage:
|
|
<https://github.com/libfuse/>
|
|
although chances are your distribution already has that library
|
|
installed if you've installed the "fuse" package itself.
|
|
|
|
See <file:Documentation/filesystems/fuse.rst> for more information.
|
|
See <file:Documentation/Changes> for needed library/utility version.

If you want to develop a userspace FS, or if you want to use
|
|
a filesystem based on FUSE, answer Y or M.

This FUSE extension allows character devices to be

If you want to develop or use a userspace character device

The Virtio Filesystem allows guests to mount file systems from the

This allows bypassing guest page cache and allows mapping host page
|
|
cache directly in guest address space.
|
|
|
|
If you want to allow mounting a Virtio Filesystem with the "dax"
|
|
option, answer Y.
