Hey Subrata Great to hear from you. I was working on a patch that touches cpuset, and mis-understood the doc, hence the patch. But I haven't worked on it after that, as I was occupied with something else. Thanks a lot for pointing me to the LTP test cases. It should help me. Surely, would use it when I get back to it, after I am back from vacation and and report my experience. :) Thanks Nikanth > > > > > > > > > > --- > > > > diff --git a/Documentation/cgroups/cpusets.txt > > b/Documentation/cgroups/cpusets.txt > > index f9ca389..1d7e978 100644 > > --- a/Documentation/cgroups/cpusets.txt > > +++ b/Documentation/cgroups/cpusets.txt > > @@ -777,6 +777,18 @@ in cpuset directories: > > # /bin/echo 1-4 > cpus -> set cpus list to cpus > > 1,2,3,4 > > # /bin/echo 1,2,3,4 > cpus -> set cpus list to cpus > > 1,2,3,4 > > > > +To add a CPU to a cpuset, write the new list of CPUs > > including the > > +CPU to be added.
