Subject: [PATCH] btrfs: update the comment of btrfs_control_ioctl()
Date: Tue, 4 Feb 2020 12:51:56 +0800 [thread overview]
Message-ID: <20200204045156.1662-1-Damenly_Su@gmx.com> (raw)
From: Su Yue <Damenly_Su@gmx.com>
Btrfsctl was removed in 2012, now the function btrfs_control_ioctl()
is only used for devices ioctls. So update the comment.
