From 2e10c46d0906b1a1ec40e8f5005ccb63125dcd9e Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Tue, 14 Mar 2023 11:06:25 +1100 Subject: [PATCH 112/125] mdopen: always try create_named_array() mdopen() will use create_named_array() to ask the kernel to create the given md array, but only if it is given a number or name. If it is NOT given a name and is required to choose one itself using find_free_devnm() it does NOT use create_named_array(). On kernels with CONFIG_BLOCK_LEGACY_AUTOLOAD not set, this can result in failure to assemble an array. This can particularly seen when the "name" of the array begins with a host name different to the name of the host running the command. So add the missing call to create_named_array().
