Looks good to me, but I wonder if this part:

                r = call->request;
-               r->time_low                     = ntohl(b[0]);
-               r->time_mid                     = ntohl(b[1]);
-               r->time_hi_and_version          = ntohl(b[2]);
+               r->time_low                     = b[0];
+               r->time_mid                     = htons(ntohl(b[1]));
+               r->time_hi_and_version          = htons(ntohl(b[2]));
                r->clock_seq_hi_and_reserved    = ntohl(b[3]);
                r->clock_seq_low                = ntohl(b[4]);
 
should be considered a bugfix and split out into a
separate patch. From what I understand about the mess in UUID
formats, the time fields can either be big-endian (as defined)
or little-endian (for all things Microsoft), and you are changing
the representation from CPU-specific to big-endian, which makes
it different for x86 and most ARM at least.
