Exercise the situation that cause ext4 to BUG_ON() when we use zero range to zero a range which starts within the isize but ends past the isize but still in the same block. This particular problem has only been seen on systems with page_size > block_size. This tests exercises the problem fixed in kernel with commit 0f2af21aae11972fa924374ddcf52e88347cf5a8 ext4: Allocate entire range in zero range Signed-off-by: Lukas Czerner <lczerner@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
