In [0], Andrew noted a code quality issue in the implementation of blk_find_first and blk_find_next. This led to the observation that the logic of these functions was also likely incorrect, and based on a quick check it seemed the functions were unused outside of test code, which did not exercise the potential failure case, so we felt they should be removed. In [1], a test patch which illustrates the failure in sandbox is provided for reference. Because a more thorough check agrees that these functions are unused, they are currently incorrect, and fixed/removable flags on block devices prior to probe are unreliable, just remove these functions instead of fixing them. All potential users should have used blk_first_device_err instead anyway. CI results at [2].
