[PATCH] USB: update usbmon, fix glued lines
This update contains one bug fix: some lines can come out truncated,
because of the safety cutoff. This happened because I forgot to update
the size when status packets began to be printed.
The rest is:
- Comments updates
- Allow snooping with pkmap on x86_64, which is cache-coherent
- Enlarge event buffers (certainly we can have a couple of pages)
- Add event counter
First touch upon usbmon for 2.6.18.
