+EDs are now allocated dynamically from their device's pool. Root hub
+status changes should stop the infinite "no device connected" messages
+that occurred after removing a device.
+
+TODO:
+
+~ Add the concept of a td_group to lump TDs associated with a single
+ data transfer request from the higher layers. This will be needed
+ for bulk and all larger transfers that will span multiple TDs but
+ which need to allocate/free them as a group as things happen. I
+ am thinking about create_td_group and free_td_group functions...
+~ Add bulk transfer support.
+~ Add Isochronous transfer support. These have their own special
+ format TDs to allow for several DMA data pointers. Kinda neat, but
+ likely harder to use through a generic interface in practice.
+~ Support dynamic allocation & growth of the TD/ED pools. Merge them
+ into global pools rather than a today's static per device allocation.
+
+KNOWN BUGS:
+
+~ Unplugging a hub causes khubd to Oops. I don't think this is
+ directly related to OHCI, but due to the fact that the interrupt TD
+ for the hub is never stopped. We need a usb_release_irq() that gets
+ called using the "IRQ handle" that should be returned by
+ usb_request_irq().

- on the next line (correctly) says that EINVAL should be
- returned. Under the same conditions.
X * rename's handling of races is, erm, not optimal. Looks like I know
X what to do, but this thing needs some more cleanup - we can
X take care of almost all races in VFS and be much more graceful

X But it's a lot of changes to lookup and dcache code, so it will
X go after the fs drivers' cleanup.
