ext4dev stability

[Jason Voorhees <jvoorhees1@gmail.com>]

Hi people:

I was reading a little about ext4 support in Lenny and I know it isn't
ready yet, just trough ext4dev module/filesystem. If I decide to
create a ext4dev filesystem, and mounting it with the option
'nodelalloc' (according to
http://ext4.wiki.kernel.org/index.php/Ext4_Howto), can I have a stable
ext4 filesystem to use in production? Or even disabling 'delayed
allocation' in ext4dev in Lenny is still not recommendable to use in
production systems?

I just want to use an ext4 filesystem without having to recompile my
kernel nor using testing repositories nor losing the stability group
of packages provided by Debian Lenny.

What would you suggest me?

Thanks
