From 83c5efc97dcaf63fb49243ce371fb4e74745a1d8 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 29 Aug 2024 09:05:07 +0300 Subject: [PATCH] nvme: set BLK_FEAT_ZONED for ZNS multipath disks The new stricter limits validation doesn't like a max_append_sectors value to be set without BLK_FEAT_ZONED. Set it before allocation the disk to fix this instead of just inheriting it later.
