Hey rsync, Seems like there was an effort a while back to make use of POSIX_FADV_DONTNEED on linux [1]. Though the linux patches landed, apparently the rsync ones never did.
Over a decade later we live in a different world. Linux is using the new-ish MGLRU on many distros, and (~6.3+) even has support for POSIX_FADV_NOREUSE [2], which was dismissed in prior discussions for lack of support. Maybe it's time to re-evaluate the utility of posix_fadvise in rsync?
