svn commit: r185902 - head/sys/boot/zfs

[Paul Saab]

Author: ps
Date: Thu Dec 11 02:23:49 2008
New Revision: 185902
URL: http://svn.freebsd.org/changeset/base/185902

Log:
  Avoid a double free in devopen by not freeing the device structure
  in zfs_dev_open.  This stops a panic in the loader when trying to
  read from a zfs device and no zfs devices exist.
