From d97572f5a59ca1ddde9971a79d47c9ea4db5891b Mon Sep 17 00:00:00 2001 From: Jes Sorensen <Jes.Sorensen@gmail.com> Date: Wed, 29 Mar 2017 15:23:50 -0400 Subject: [PATCH] util: Introduce md_get_disk_info() Git-commit: d97572f5a59ca1ddde9971a79d47c9ea4db5891b Patch-mainline: mdadm-4.0+ References: bsc#1069165, bsc#1069167, bsc#1068030 This removes all the inline ioctl calls for GET_DISK_INFO, allowing us to switch to sysfs in one place, and improves type checking.
