I would like to announce the availability of version 0.1 of UVFS, yet another user space filesystem kit. UVFS provide an interface to almost all kernel VFS methods in user space with acceptable overhead. It comes with a sample in memory filesystem as documentation.

As far as I can determine UVFS is quite robust but I would love to have some independent confirmation of that. I would also be delighted if someone more familiar with the linux VFS than I, were to give the code a once-over.

The current version of UVFS only supports a single instance of a given filesystem type. That will be addressed in the next public release.

UVFS can be found at http://www.sciencething.org/geekthings/index.html .

How do you solve deadlocks on writing?

[Imagine so many dirty buffers are in memory that your filesystem-in-userspace-daemon was swapped out?]

[Miklos, Cc-ed to you. You have that problem too. And it probably has same solution like those untrusted filesystems -- back it up by a file.]
