Did you reply to Chuanxiao's review comments yet? He said:
"So to implement your scenario, how about only add mmc_blk_issue_sanitize_rq() for REQ_SANITIZE but not touch mmc_blk_issue_secdiscard_rq()? With your changes in mmc_blk_issue_secdiscard_rq(), eMMC4.5 device will be failed to operate secure trim/erase for REQ_SECURE request."
