Test that a file fsync works after punching a hole for the same file range multiple times, and that after log/journal replay the file's content and layout are correct. This test is motivated by a bug found in btrfs, which is fixed by the following linux kernel patch: "Btrfs: fix hole punching when using the no-holes feature" Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
