[PATCH v4] Fixes for PCI backend for 3.19
From: Konrad Rzeszutek Wilk
Date: Fri Nov 21 2014 - 17:18:27 EST
The last time I posted these patches: https://lkml.org/lkml/2014/7/8/533
was so long ago that I don't even remember most comments. The only
one that stuck in mind was David's recommendation to add a new PCI API
call and use that. See patch #6 and #7.
The original posting (v3) had an extra patch that would do slot and
bus reset using do_flr SysFS attribute. I will revisit that once I am
done with this patchset.
I also seem to have had in my a bunch of 'SoB' from David - which
makes no sense - unless I pulled from his tree. Anyhow wherewere
I saw them I removed them.
Please take a look and comment. If I missed some comment from months
ago hopefully the new version has clarified them.
