Reiser4 in 2.6.14-rc1-mm1

Reiser4 in 2.6.14-rc1-mm1

[Lexington Luthor]

Hi,

Do the reiser4 updates in the new -mm kernel include the compression plugin?

If so, I would love to be able to try it out on my laptop (only 20GB 
disk). Do I have to mkfs again, or can I enable it at mount time, or is 
it a per-file or per-directory attribute like NTFS?

Hello.
It was possible earlier to set it per directory using pseudo-file interface,
but 2.6.14-rc1-mm1 does not contain it already. We will try to post and
update the appropriate patch, but anyway using cryptcompress plugin
can crash your system.

Thanks,
Edward.

How stable is it? Last I read, namesys was aiming to have the compress 
plugin working in reiser4 to be merged into 2.6.14 for the vanilla 
kernel release. Not that that matters, as I use -mm mostly on my test 
machines.

If it is possible to use it now, I would love to try - I don't mind 
crashes on my test boxes and having ~50% more space would be great :)

I do not keep a track of it. As I remember mmap() is defuncted,
also loop devices on such files fails to work. Send us a private
message (CC reiserfs-dev_at_namesys_com) if you really want to
build and play with it in debug mode.
