Other than the detail of allowing a newline from doing:
echo > cpus
to work, I'm ok with this patch. It passes my cpuset_test,
and seems to allow unpopulating cpusets, as advertised.
Aha - as I was writing this, I noticed that the command:
echo -n '' > cpus
does -not- work! The echo command recognizes that as a write
of zero non-null bytes, and skips the write altogether.
We have to add the code to handle an input line consisting of
just a bare newline, to mean an empty mask. Well, we don't
-have- to. But writing a single nul byte in shell script will
challenge most shell script hackers.
