Ok, series applied to net-next minus patches #5 and #6.
Thank you.

Hi,
I am trying to bring up a Intel XL710 4x10G Intel card using the
latest mainline top-of-tree.
The problem is that "ifconfig up" and "ifconfig down" do not take
effect at the link state level.
I tracked the problem down to i40e_force_link_state() when it is
called from i40e_down().
It calls i40

Hi all,
this series adds support for the IOCB_CMD_POLL operation to poll for the
readyness of file descriptors using the aio subsystem. The API is based
on patches that existed in RHAS2.1 and RHEL3, which means it already is
supported by libaio. To implement the poll support efficiently new

Use straightline code with failure handling gotos instead of a lot

->get_poll_head returns the waitqueue that the poll operation is going

for the poll, unlike some current drivers that use two waitqueues for
different events. But now that we have keyed wakeups and heavily use
