(I have none) 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?
