I think we can expect this to use a bit more CPU time, but unless
you're very tight on that you probably shouldn't expect any throughput

Hi,
Here's my first series for v4.10. These are the changes:

Currently when configuring the cab queue the scheduler is configured

iwlmvm currently uses dev_coredumpm() to collect multiple

Hi,
Here are a few fixes that I'm planning to send for v4.9. Nothing
major, here's what they are about:
* some fixes for suspend/resume with unified FW images;
* a fix for a false-positive lockdep report;
* a fix for multi-queue that caused an unnecessary 1 second latency;
*
From: Luca Coelho
With unified images, we need to make sure the net-detect scan is
stopped after resuming, since we don't restart the FW. Also, we need
to make sure we check if there are enough scan slots available to run
it, as we do with other scans.
