vnode interlock to protect the knote fields [1]. The locking assumes that shared vnode lock is held, thus we get exclusive access to knote either by exclusive vnode lock protection, or by shared vnode lock + vnode interlock. Do not use kl_locked() method to assert either lock ownership or the fact that curthread does not own the lock. For shared locks, ownership is not recorded, e.g. VOP_ISLOCKED can return LK_SHARED for the shared lock not owned by curthread, causing false positives in kqueue subsystem assertions about knlist lock. Remove kl_locked method from knlist lock vector, and add two separate assertion methods kl_assert_locked and kl_assert_unlocked, that are supposed to use proper asserts. Change knlist_init accordingly. Add convenience function knlist_init_mtx to reduce number of arguments for typical knlist initialization.
