You're kidding right? Is a struct urb that big? What is the memory footprints you are dealing with here that this makes a difference? What about performance issues with smaller number of urbs, this change will make some device now go slower, which isn't a nice thing :( > Applying this patch to the current sierra.c driver in the kernel will make > the source identical with the version available from the sierra wireless > knowledgebase website.

I see a bugfix snuck in here that you should send separately, as it has nothing to do with the memory size changes. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
