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. - -Jeff - -- Jeff Mahoney SuSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFDEySgLPWxlyuTD7IRAoMXAJ9IozJtv2236HK1R/4bMMaK8/mrIACeMYUu tz7nPOMFTIY2dJ/j9DXjMG0= =lGWE -----END PGP SIGNATURE-----
