A comment on Cache eviction: when are randomized algorithms better than LRU? (2014). Parent comment
For memory mapped regions there is madvise() DONT_NEED to tell the kernel to that you won't need this data again so don't bother with the disk cache.
For the CPU cache the non-temporal instructions MOVNTI that tells the CPU to not bother caching the move to prevent cache pollution.
