[Dazuko-devel] nullfs 0.0.1 posted

[John Ogness]

Hi,

I have posted version 0.0.1 of nullfs. This is a pass-through
stackable filesystem. It's only purpose is to test that the stackable
filesystem code is correctly implemented.

It is hoped that nullfs will eventually become the official testing
ground for stackable filesystems and may provide a template/example
for those interested in developing their own stackable filesystems on
Linux.

Eventually DazukoFS will be based on nullfs (instead of the FiST
project). In my opinion this first version of nullfs is already more
stable than the latest FiST release.

If you are interested in helping bring DazukoFS to a stable release,
you can help a lot by testing nullfs. I plan to soon post a new
experimental pre-release of Dazuko 3.0, this time based on nullfs
instead of FiST. Improvements in nullfs will directly help to improve
Dazuko 3.0.

The only missing feature of nullfs is write-support for memory mapped
files. Once I get that implemented, I will be posting nullfs to the
Linux kernel mailing list to see if we can get it mainline. This would
be an important first step towards moving Dazuko into the mainline
kernel.

Be sure to read the README included in the nullfs distribution. nullfs
will work as a kernel module and without any kernel patches. Linux
2.6.21 or higher is required.
