The device ops->get_bb_tbl() takes a callback, that allows the caller to use its own callback function to update its data structures in the returning function. This makes it difficult to send parameters to the callback, and usually is circumvented by small private structures, that both carry the callers state and any flags needed to fulfill the update. Refactor ops->get_bb_tbl() to fill a data buffer with the status of the blocks returned, and let the user call the callback function manually. That will provide the necessary flags and data structures and simplify the logic around ops->get_bb_tbl(). Signed-off-by: NMatias Bjørling <m@bjorling.me> Signed-off-by: NJens Axboe <axboe@fb.com>
