Re: [linux-usb-devel] Re: usb-storage not suitable for swapping

Seems simple enough.  It's possible even to get rid of most
conditional logic ... add "int mem_flags" to "struct usb_device",
initialize it to GFP_KERNEL, and use that field any time a
driver would otherwise use SLAB_KERNEL.  Storage
could set it to GFP_NOIO.
