Hook open and open64 libc calls to avoid updating atimes while searching or the like.
atimes are useful for a lot of reasons so you may not want to disable them completely. However with advanced searching tools like ripgrep you'll tend to search a lot more files than actually needed, thus updating atimes of a lot of files. You'll lose track of last actual use of the files as well as being slow because of disk writes.
This is known to work with ripgrep on Linux with glibc.
