Subject: [RESEND PATCH] block: move tag field position in struct request
Date:   Sun,  9 Jun 2019 05:15:51 +0900

__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.
