Keep in mind, that host page size can be smaller than target page size too.
That's the reason why host brk (brk_
do_brk() minimizes calls into target_mmap() by aligning the address
with host page size, which is potentially larger than the target page
size. However, the current implementation of this optimization has two
bugs:
- The start of brk is rounded up with the host page size while brk
