Looks obviously correct and tests okay. Ctrl-c in any situation
does the right thing now. Before your refactoring of ib_umem, the
older version of ib_umem_release_on_close() did not have this
trylock optimization. This new buggy code appears not to have shown
up in any releases yet, fortunately.
Thanks for the quick fix.
