I've done testing with it, and it's been ok. I haven't heard any bug
reports, but I haven't heard any "hey it works" comments either. It
should be pretty stable - the only thing I'm concerned about is how it
deals with I/O errors. That part of the patch will be dependent on my
developing better i/o handling for reiserfs in general. That patch is
also mostly done, but needs more testing.
