[src/trunk]: src/tests/fs Add basic test for umapfs functionality.
details: https://anonhg.NetBSD.org/src/rev/f5bda9d2bccd
branches: trunk
changeset: 753476:f5bda9d2bccd

description:
Add basic test for umapfs functionality.
XXX: the reverse mapping case (last subsubtest in t_basic) does
not make any sense, but apparently that how umapfs works. I'm not
familiar enough with the code to determine if this is a wanted
feature or a pure and simple bug.
