There's no problem with uint32_t vs u32 - either will do.  u32 is the
pre-stdint.h Linux definition of a 32-bit unsigned integer.  There's
no reason why uint32_t isn't perfectly acceptable.  It's a matter of
author taste which gets used.  (Except where modifications are to an
existing chunk of code using one or the other - where consistency then
matters more.)
