There is no need for signedness on these QID fields for 9p.

You should mention here the changes you made on top of Antonios
original patch. Something like:

[CS: - also convert path
     - adapted trace-events and donttouch_stat()]

I was expecting to see PRIu64 for an uint64_t but I now realize that %d
seems to be used all over the place for unsigned types... :-\

At least, please fix the masks of the lines you're changing in this
patch so that unsigned are passed to "u" or PRIu64. The rest of the
mess can be fixed later in a followup.

Haven't seen that comment style in the git logs. Any example hash for that?

If you don't mind I will restrict it to your latter suggestion for now, that 
is adjusting it using the short format specifiers e.g. "u", the rest would IMO 
be out of the scope of this patch series.

Too bad that no format specifier warnings are thrown on these.
