From 451f0b6f4c44d7b649ae609157b114b71f6d7875 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 25 Feb 2022 19:14:40 +0100 Subject: [PATCH] block: default BLOCK_LEGACY_AUTOLOAD to y As Luis reported, losetup currently doesn't properly create the loop device without this if the device node already exists because old scripts created it manually. So default to y for now and remove the aggressive removal schedule.
