Hi Thomas,
Thanks for your review.
According to the definition of the macro PRIu32(# define PRIu32 "u"),
using PRIu32 works the same as using %u to print, and using PRIu32 to print
is relatively rare in QEMU(%u 720, PRIu32 only 120). Can we continue to use %u
to
print max_vq and vq in this patch.
Of course, this is just my small small suggestion. If you think it is better to
use
PRIu32 for printing, I will send patch V2.
Looking forward to your reply.
Thanks,
Alex
