Hello David,

This patch doesn't seem to have made it to linux-next (for May 21),
yet. Could you kindly re-check?

Thanks
Suresh

Hello David,

I don't find this patch in linux-next, yet. Did you find any problem
with this patch?
Just trying to make sure it is not getting lost in the pile..

Thanks
