From 2f578aaf51624aa6fcff041fc7dc5c2d4dfa447f Mon Sep 17 00:00:00 2001 From: Minwoo Im Date: Sun, 9 Jun 2019 05:15:51 +0900 Subject: [PATCH] block: move tag field position in struct request __data_len and __sector are internal fields which should not be accessed directly in driver-level like the comment above it. But, tag field can be accessed by driver level directly so that we need to make the comment right by moving it to some other place.
