Assert this. In the reported panic, vdestroy() fired the assertion "vp has namecache for ..", because pseudofs may end up doing cache_enter() with reclaimed dvp, after dotdot lookup temporary unlocked dvp. Similar problem exists in ufs_lookup() for "." lookup, when vnode lock needs to be upgraded. Verify that dvp is not reclaimed before calling cache_enter().
