This is a note to let you know that I've just added the patch titled
Drivers: hv: vmbus: Don't wait after requesting offers
to my char-misc git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-next branch.
The patch will show up in the next release of the linux-next tree

Subject: Drivers: hv: vmbus: Don't wait after requesting offers
Don't wait after sending request for offers to the host. This wait is
unnecessary and simply adds 5 seconds to the boot time.
