I initally submitted kcalloc() with just one parameter but Arjan
wanted it to be similar to standard calloc() so we could check for
overflows. I don't see any reason not to introduce kzalloc() for the
common case you mentioned (as suggested by Denis).
kzalloc it is, then.
By the way I did a quick measurement to see how much we could gain in
kernel size by doing this. This is with a 2.6.11-rc2, defconfig kernel:
with kmalloc+memset:
vmlinuz: 5521614
bzImage: 2005274
with kzalloc:
vmlinuz: 5513422
bzImage: 2003927
So we gain 8kB on the uncompressed image and 1347 bytes on the
compressed one. This was just a dumb test and actual results might be
better due to smarter human cleanups.
Not a spectacular gain per se, but the increase in code readability is
still worth it, IMHO.
