From 7fc18728482b1a29bd7b8439a0ae7b3f23e097d1 Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Wed, 26 May 2021 06:24:56 +0900 Subject: dm: move zone related code to dm-zone.c Move core and table code used for zoned targets and conditionally defined with #ifdef CONFIG_BLK_DEV_ZONED to the new file dm-zone.c. This file is conditionally compiled depending on CONFIG_BLK_DEV_ZONED. The small helper dm_set_zones_restrictions() is introduced to initialize a mapped device request queue zone attributes in dm_table_set_restrictions().
