Konstantin Belousov 5673e3cb08 The cache_enter(9) function shall not be called for doomed dvp. ... 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().
