You're missing the point here, I think. Try downloading a large (multi-gigabyte) torrent on ext4 or xfs or btrfs; see what the resulting file layout looks like if your client does not preallocate. Now use a client that preallocates the space and try again. Calling fallocate() first for the full file size will help on all these filesystems (well, TBH, I have not tested it on btrfs). If there are well-defined interfaces to give hints to the filesystem about the ultimate state of a file, it's a nice feature, not a bug. Sure, filesystems should do the best they can in the absence of hints, but performing well (or better) _with_ a hint is not indicative of a bug.
I apologize. I'm a rambling idiot. Please carry on without me. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
