From 7e0adbfc20c50b021e425662834a492f958efee7 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 7 Jun 2020 17:31:19 +0200 Subject: md: rewrite md_setup_drive to avoid ioctls md_setup_drive knows it works with md devices, so it is rather pointless to open a file descriptor and issue ioctls. Just call directly into the relevant low-level md routines after getting a handle to the device using blkdev_get_by_dev instead.
