[PATCH 0/2] *** Latency Histogram ***

[Binoy Jayan]

Hi,

I was looking at these RT kernel patches and was wondering why it has
not been upstreamed yet. I have made a few changes to these patches to
make it compliant with upstream submission process. Also did a minimal
testing on my msm board. Can some one from rt kernel team shed some
light on why this is not upstreamed yet? Also if there some way to test
this throroughly on a board with a high resolution timer running mainline
(and not rt) kernel.
