Erm, the suspend-path recursion was removed most of a year ago... agreed that the matching resume path updates didn't merge at tha time, and fixes there are needed. > One smidgeon of recursion remains: When a remote wakeup request comes in, > the code still does resume all the interfaces along with the device.

With and without CONFIG_USB_SUSPEND? I suppose I was just a bit surprised to see how much resume-side recursion could be removed and have things still work. So I'm curious about just how much is known to work. ;) As for testing all this, I guess I'm suspecting that being able to do it in a couple groups might be good. And patch seven-of-nine is a bout where I start wanting to do very separate tests. :) - Dave _______________________________________________ linux-usb-devel@lists.sourceforge.net To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
