So, yes, UP testing (presumably, with PREEMPTION) is useful. Please, wait a short time for new patch. Current patch has two issues: 1. recent BO_NEEDSGIANT changes prevent patch from applying. I need to do a merge. 2. I have fixed deadlock that appears when shapshot is taken on quota-enabled fs (this deadlock is specific to my patch). Supposely, this is problem reported by Kris Kennaway. --XsQoSWH+UP9D9v3l Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (FreeBSD) iD8DBQFEUcXfC3+MBN1Mb4gRAqHkAJ4i8smoq2Wcb6oDEBwrmWnquJ5WXgCgs4yR PZKrQJZYbg2pYnGpyYiTH6E= =hgVk -----END PGP SIGNATURE----- --XsQoSWH+UP9D9v3l--
