The other option is that it's broken up into two new flags the first
MREMAP_MUSTMOVE which can be used regardless of whether or not you're
leaving the original mapping mapped. This would do exactly what it
describes: move the mapping to a new address with or without
MREMAP_FIXED, this keeps consistency with MAYMOVE.
The second flag would be the new MREMAP_DONTUNMAP flag which requires
MREMAP_MUSTMOVE, again with or without MREMAP_FIXED.
What are your thoughts on this?
