This means we only support keep-size and pouch_hole.
And it seems pouch_hole will also imply keep-size.

[RFC] add support for fallocate()
fallocate() is linux specific and will preallocate the space on disk for
the entire file. FALLOC_FL_KEEP_SIZE does not change the filesize as
reported by stat(). An aborted transfer will have preallocated disk space
which is not "visible" via stat(). This shouldn't matter unless the user
does complet his transfer.
An alternative would be to use ftruncate() and shorten the file to the
size whi...
