Subject: [PATCH v3 4/4] btrfs: sysfs, rename device_link add,remove functions
Date: Wed, 12 Feb 2020 17:28:13 +0800	[thread overview]
Message-ID: <1581499693-22407-5-git-send-email-anand.jain@oracle.com> (raw)
In-Reply-To: <1581499693-22407-1-git-send-email-anand.jain@oracle.com>

Since commit 668e48af7a94 (btrfs: sysfs, add devid/dev_state kobject and
device attributes), the functions btrfs_sysfs_add_device_link() and
btrfs_sysfs_rm_device_link() does more than just adding and removing the
device link as its name indicated.

Its time to rename them.

No functional changes.
