Please consider this patch series for the next merge window. Changes compared to v1: - Fixed an issue where the error code was clobbered in resp_write_same()= and __resp_write_same() when fetch_to_dev_buffer() fails (John Garry and sashiko-bot). - Fixed return value handling in resp_read_dt0() and resp_write_dt0(): previously a positive byte count returned by do_device_access() was incorrectly treated as a SCSI status code and returned to the caller. = Now, the SCSI status is passed via an output pointer and only negative retu= rn values trigger an error return (sashiko-bot). - Improved lock context annotations: * Annotated existing rwlock_t members (&sip->macc_data_lck, &sip->macc_sector_lck, &sip->macc_meta_lck) directly with __acquires= / __releases instead of defining and embedding dummy context lock stru= cts in struct sdeb_store_info. * Dropped the unwarranted __context_unsafe() annotation from sdeb_data_read_lock(). * Updated the commit descriptions to match the code changes. Thanks, Bart.
