When we upgrade a vnode lock from shared to exclusive during a name cache lookup, fail the lookup with EBADF if the vnode is invalidated while we are waiting for the exclusive lock. Also, for correctness (though I'm not sure it can occur in practice), downgrade an exclusively locked vnode if it should be share locked. Tested by: pho |
