Follow-up Comment #12, bug #20478 (project lwip):

re comment #11:

Exactly, that's how I'd think it would be better.

SYS_LIGHTWEIGHT_PROT=1).

Does it? It's one 'if' statement less, which means less code.
We could argue here if the if statement is more code than the 'return NULL'
or the 'SYS_ARCH_UNPROTECT'... For a good compiler, this probably wouldn't
make a difference, but why not help the other compilers?

After all, I think the code is better to read that way.
