commit 9a49157deeb23581fc5c8189b486340d7343264a upstream. Some low-level drivers (LLD) access block layer crypto fields, such as rq->crypt_keyslot and rq->crypt_ctx within `struct request`, to configure hardware for inline encryption. However, SCSI Error Handling (EH) commands (e.g., TEST UNIT READY, START STOP UNIT) should not involve any encryption setup. To prevent drivers from erroneously applying crypto settings during EH, this patch saves the original values of rq->crypt_keyslot and rq->crypt_ctx before an EH command is prepared via scsi_eh_prep_cmnd(). These fields in the 'struct request' are then set to NULL. The original values are restored in scsi_eh_restore_cmnd() after the EH command completes. This ensures that the block layer crypto context does not leak into EH command execution.
