From 3093a479727be194996dbc40f803711af5877be4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 20 Jul 2020 08:12:49 +0200 Subject: block: inherit the zoned characteristics in blk_stack_limits Lift the code from device mapper into blk_stack_limits to inherity the stacking limitations. This ensures we do the right thing for all stacked zoned block devices.
