The patches all look good to me. Patch three again could use some
information describing that it replaces an interruptible semaphore
with an uninterruptible mutex, fixing a bug in the process.

BTW, there is no need to list the dependencies in each patch
when posting a series, as the default assumption is that they
need to be applied in sequence.
