Hello, This patch set enables the use of PCI Express link up and link down events for Hotplug or Unplug. Resending the patch after taking care of review comments, splitting patch into multiple smaller patches, and incorporating the conclusions drawn from the discussion here: http://marc.info/?t=138611014300001&r=1&w=2 Due to splitting of the patch, 4 new patches are added to the patchset, although the content is almost the same. Patch v2 [1/4] = Patch v3 [1/8] Patch v2 [2/8] = Patch v3 [2/8] + Patch v3 [3/8] + Patch v3 [4/8] + Patch v3 [5/8] + Patch v3 [6/8] Patch v2 [3/4] = Patch v3 [7/8] Patch v2 [4/4] = Patch v3 [8/8] (As a side effect, this patch also fixes the bug https://bugzilla.kernel.org/show_bug.cgi?id=65521 ) I'd appreciate if you could please review and provide me with any comments.
