From c6761a9ed329dd41fee09dc2926126768e5ca34c Mon Sep 17 00:00:00 2001 From: Anand Jain Date: Thu, 21 Nov 2019 17:33:32 +0800 Subject: [PATCH] btrfs: sysfs, btrfs_sysfs_add_fsid() drop unused argument parent Commit 24bd69cb ("Btrfs: sysfs: add support to add parent for fsid") added parent argument in preparation to show the seed fsid under the sprout fsid as in the patch [1] in the mailing list. [1] Btrfs: sysfs: support seed devices in the sysfs layout But later this idea was superseded by another idea to rename the fsid as in the commit f93c39970b1d ("btrfs: factor out sysfs code for updating sprout fsid"). So we don't need parent argument anymore.
