Does this make any practical difference?
I mean, are you aware of any problem that gets fixed by this patch, or
even any kind of performance degradation?
"common/dlmalloc.src" says:
calloc(size_t unit, size_t quantity);
Returns a pointer to quantity * unit bytes, with all locations
set to zero.
Multiplication being commutative, I see zero effect in this patch?
Best regards,
Wolfgang Denk
