This seems to miss any explanation and 6 out of 7 patches.

See linux-fsdevel for entire patch set.

But only one made it to linux-xfs, so please fix your patch sending.

(f)pathconf on it's own is useless because I need to get this
information directly from the file system. Supported fallocate modes can
differ with inode flags (encrypted files, extent/indirect based files on
ext4). I also need in-kernel interface.

And that is exactly what I want you to do:  finally bite the bullet
and add pathconf inode operation.
