> it is likely Linux specific

Using it to prevent disk-full would equally apply to FreeBSD and other operating systems as Linux, on non-CoW filesystems.

Anyhow, the original motivation was early detection of disk-full not performance. I wouldn't really expect a performance benefit. I don't object to removing use of `posix_fallocate()` but as it wasn't intended as a performance improvement IMO removing it is not justified by lack of performance benefit.
