From ae5dfc56b7a96805d5a0b50eaf93b9fec8604298 Mon Sep 17 00:00:00 2001 From: Mariusz Tkaczyk <mariusz.tkaczyk@linux.intel.com> Date: Tue, 19 Jul 2022 14:48:23 +0200 Subject: [PATCH 49/61] mdadm: move data_offset to struct shape Patch-mainline: mdadm-4.2+ References: jsc#PED-1009 Data offset is a shape property so move it there to remove additional parameter from some functions.
