No you don't. There's absolutely nothing wrong with putting them at
the top. In fact, it is simpler, really, than having to go hunting
for dozens of different declarations. As someone who has spent a lot
of time looking at code, the time wasted looking for these damn-fool
things really adds up.
and in a complicated function, if you have them all over the place you
have no idea as to what the potential stack usage of the function is..
This matters in the kernel.
The declared local variables are neither a lower *nor* an upper bound
for stack usage.
