I think moxfyre is absolutely right. There are already so much
different approches, but e2compr is the only one that fullfills
the needs at my acutal project.

So, we will need to port e2compr to the toplevel 2.6-kernel.

1.) I think one of the first steps would be to make add e2compr
to cvs for easier development.

2.) The last working patch was for kernel 2.6.10. So, at first,
I would be thankful for any hints on what changed in the kernel
since that time. Changes would be in vfs and ext2-code, I guess.

3.) Maybe it would be also possible to make one unique patch, to
adopt e2compr to ext2 and ext3. Maybe we should overthink the kernel
architekture. Maybe the data-compression should happen between vfs and
the filesystem implementation. Like this:

VFS
------------
COMPRESSION + ENCRYPTION
------------
FS (ext2, ext3 ...)

Any ideas?

I would encourage everybody, to participate or at least give
me some hints, what has to be done and how!!!!
