[PATCH 4.18 146/197] btrfs: rename local devices for fs_devices in btrfs_free_stale_devices(

From: Greg Kroah-Hartman
Date: Thu Sep 13 2018 - 10:01:59 EST


4.18-stable review patch. If anyone has any objections, please let me know.

------------------

From: Anand Jain <anand.jain@xxxxxxxxxx>

[ Upstream commit fa6d2ae540a200a17bb7ee769f9df22d411c9404 ]

Over the years we named %fs_devices and %devices to represent the
struct btrfs_fs_devices and the struct btrfs_device. So follow the same
scheme here too. No functional changes.
