--KsGdsel6WgEHnImy Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable > Argh! The patch was still broken even after this fix. FWIW I just checked and one of my machines which was using both zfs_thread_priority.diff and zfs_zinactive_deadlock.diff has survived a night of package building without ZIL disabled. This would very rarely, if at all, happen with ZIL enabled traditionally. On 8-CURRENT I only tried it onces with ZIL enabled and it did hang, and now it didn't. I guess I'm not triggering the other deadlock that you indicate is still present. I'll hold off more testing for a bit since it sounds from other posts like there are yet new patches in the pipeline. --=20 / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller <peter.schuller@infidyne.com>' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org --KsGdsel6WgEHnImy Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (FreeBSD) iEYEARECAAYFAkn5bY8ACgkQDNor2+l1i30oUwCgx755Bq7S9EtuuHhFSEPBP4yx iZIAoNF600Ldzx4Co0Rp0MQYpp+mViZR =ls3N -----END PGP SIGNATURE----- --KsGdsel6WgEHnImy--
