> Is it desirable for this check to be run for each iteration of the loop.
thats is not really the case. that statemet is executed exactly once.
the first check in the loop body looks for the multiboot header
signature and continues the loop if not found. once that check
passes the iteration ends as we return at the bottom of the loop
body, and there are no other continues.
for (mbh_offset = 0; mbh_offset <= (len - 12); mbh_offset += 4)
{
/* Search for a multiboot header */
mbh = (struct multiboot_header *)(headerbuf + mbh_offset);
if (mbh->magic != MULTIBOOT_MAGIC
|| ((mbh->magic+mbh->flags+mbh->checksum) & 0xffffffff))
{
/* Not a multiboot header */
continue;
}
