Heh, I think that's going a bit too far. Of course mico-optimizations
usually make the system go faster, but not enough to show out of the
noise, and micro-optimizations most of the time just make the code
harder to understand and more error prone.
A lot of the patches in this patch set could just do the:
struct foo bar = { 0 };
This would let gcc optimize what needs to be done, and avoids a function
call to memset.
