Subject: [PATCH v2 5/5] btrfs: sysfs, merge btrfs_sysfs_add devices_kobj and fsid
Date: Thu, 21 Nov 2019 17:33:34 +0800	[thread overview]
Message-ID: <1574328814-12263-6-git-send-email-anand.jain@oracle.com> (raw)
In-Reply-To: <1574328814-12263-1-git-send-email-anand.jain@oracle.com>

Merge btrfs_sysfs_add_fsid() and btrfs_sysfs_add_devices_kobj() functions
as these two are small and they are called one after the other.

Signed-off-by: Anand Jain <anand.jain@oracle.com>

v2: nothing in specific to this patch actually, but the changes
    before this patch makes v1 apply fail. So fixed in v2.
