Why do you consider it _dangerous_ for the manpages to replace __u32
with uint32_t, when we know by construction that the two types will
always be the same? Alejandro's preference for the types standardized
by ISO C seems perfectly reasonable to me for documentation; people
reading the documentation can be expected to already know what they
mean, unlike the Linux-specifc __[iu]NN types. Also, all else being
equal, documentation should avoid use of symbols in the ISO C reserved
namespace.
If anything I would argue that it is the uapi headers that should be
changed, to use the <stdint.h> types.
