From 3d77976c3a8586ab1fb6845e2061588b7d04934f Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 27 Dec 2023 09:23:04 +0000 Subject: [PATCH] loop: don't abuse BLK_DEF_MAX_SECTORS BLK_DEF_MAX_SECTORS despite the confusing name is the default cap for the max_sectors limits. Don't use it to initialize max_hw_setors, which is a hardware / driver capacility.
