Description

The zfs vnops entry points in zfs_link() and zfs_rename() are already doing the checks for the cross-device operations, but these checks are not complete. They do not count the v_vfsp tweaks done deep in the zfs code here:

http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/common/fs/zfs/zfs_ctldir.c#925

The issue was reported by Pascal Bouchareine <>. Thanks.
