madvise ^⚠
mlock ^⚠	Locks all memory pages that contain part of the address range with `length` bytes starting at `addr`. Locked pages never move to the swap area.
mlockall	Locks all memory pages mapped into this process’ address space. Locked pages never move to the swap area.
mmap ^⚠	Calls to mmap are inherently unsafe, so they must be made in an unsafe block. Typically a higher-level abstraction will hide the unsafe interactions with the mmap’d region.
mprotect ^⚠	Set protection of memory mapping.
msync ^⚠
munlock ^⚠	Unlocks all memory pages that contain part of the address range with `length` bytes starting at `addr`.
munlockall	Unlocks all memory pages mapped into this process’ address space.
