| |
Hello,
This patch set enables the use of PCI Express link up and link down events for Hotplug or Unplug. The requirement of such a feature was originally discussed here:
http://www.spinics.net/lists/linux-pci/msg05783.html http://www.spinics.net/lists/hotplug/msg05801.html
Patch [1/4]: makes a function non-static for use by patch 2. Patch [2/4]: Contains the bulk logic to allow link events to be used for hotplug and removal. Patch [3/4]: Makes the pciehp_power_thread() lock free by making it look at a work info->req instead of slot->state. Patch [4/4]: Introduce slot->hotplug_lock to serialize the hotplug operations.
I'd appreciate if you could please review and provide me with any comments.
Thanks,
Rajat
