From 1c8327950566449e206e613c11c8232032f26787 Mon Sep 17 00:00:00 2001 From: Mariusz Tkaczyk Date: Mon, 18 Mar 2024 16:19:29 +0100 Subject: [PATCH 37/41] mdadm: set swapuuid in all handlers It is not set, so it should be 0 but it may vary on compilation settings. Set it always to 0. metadata should care to set UUID and read in proper endianness so it doesn't follow super1 concept of swapuuid to depend on endianness. It is not an attempt to fix endianness issues.
