[LTP] [PATCH] Use fallocate() to create loop device backing file

[Jan Stancek]

----- Original Message -----
> Creating large loop device backing files using tst_fill_file() on shared
> testing machines  may lead to performance issues and timeouts. Preallocating
> space using fallocate() is fast and sufficient.
> 
> Space allocation will fall back to tst_fill_file() if fallocate() fails for
> any
> other reason than lack of space.
