Might be, he could comment more.
Whoops, I replied bot forgot to reply-all. Adding a stub for posix_fadvise() is on my list of things to do, since we use it at $WORK in our custom filesystem, but the list is long and spare time is short. Nominally a technically correct implementation can do error checking and then nothing. Even after a stub is added to the OS, each filesystem must implement a VOP to do the work.
