Konstantin Belousov bf9c87c813 Be more strict when selecting between snapshot/regular mount. ... Reclaimed vnode type is VBAD, so succesful comparision like devvp->v_type != VREG does not imply that the devvp references snapshot, it might be due to a reclaimed vnode. Explicitely check the vnode type. In the the most important case of ffs_blkfree(), the devfs vnode is locked and its type is stable. In other cases, if the vnode is reclaimed right after the check, hopefully the buffer methods return right error codes.
