Test extent pre-allocation (using fallocate) into a region that already has a pre-allocated extent that ends beyond the file's size. Verify that if the fs is unmounted immediately after, the file's size and content are not lost. This is motivated by a minor issue found in btrfs where the second fallocate wouldn't update the inode's i_size on disk, fixed by the following btrfs patch: "Btrfs: add missing inode item update in fallocate()".
