Is that true? mmap still silently rounding up the length to the page size, I
assume, so even that name is misleading.
Hi Florian,
Not as far as I can tell, it's not doing that.
For both MAP_FIXED, and this new flag, the documented (and actual)
behavior is *not* to do any such rounding. Instead, the requested
input address is required to be page-aligned itself, and mmap()
should be honoring the exact addr.
I meant the length, not the address.
