I've looked through the SVN commit logs but don't see any of the associated bugids (2178259, 6440499, 6754011, 6791106, 6860045, 6860045, 6877373, 6880764, 6892298, 6900938) referenced. I've had a report of a problem that could potentially be caused by this but am still investigating it. Does anyone know if these bugs affect ZFS on FreeBSD? --=20 Peter Jeremy --ew6BAiZeqk4r7MaW Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (FreeBSD) iEYEARECAAYFAkwpIkQACgkQ/opHv/APuIeuFACgmohkJtTtGX1FiYz8OIopdv/g F2gAn2ZH8ejQFo204vbSy3DRuJe4qRiu =iROR -----END PGP SIGNATURE----- --ew6BAiZeqk4r7MaW--
