Log Message:
For ZFS on NetBSD there are a number of functions called
zfs_netbsd_{create,mknod,link,etc..} that call functions called
zfs_{create,mknod,link,etc..}.  These later functions may return a
error code along with a *vpp that is NULL.  This situation was not
handled by the zfs_netbsd_* functions and would result in a panic in a
number of cases.  The simplest to trigger it was filling up a dataset
or pool resulting in a over quota condition.  An attempt to create
another file, or directory at that point would panic.
