Hi, Vivek,
I was able to compile and boot a 2.6.31-rc1 kernel with this patchset.
I have a request could you fold up all patches and make one
consolidated patch available somewhere (makes it easier to test), may
be a git tree?
I did some quick tests with some io benchmarks and found in a simple
scenario that the scheduler worked as expected, except that it took
very long. I'll investigate further and revert back.
