Has anyone ever done an madvise(2)-type syscall for file descriptors? (or does the capability exist and I'm missing it?)
I was thinking, in playing around with stuff like cp(1) I've found that standard read(2) and write(2) of a 4-8K buffer is the fastest solution overall, in addition to providing the useful side effect of better error reporting, such as ENOSPC report. Better error reporting than the alternative I see anyway, mmap(2).
So... we have madvise, why not fadvise? I would love the capability for applications to provide hints to the OS like madvise, but for file descriptors...
