Anand Jain Nov. 18, 2019, 8:46 a.m. UTC
In preparation to add btrfs_device::dev_state attribute in
  /sys/fs/btrfs/UUID/devices/

Rename btrfs_sysfs_add_device_link() and btrfs_sysfs_rm_device_link() to
btrfs_sysfs_add_device_info() and btrfs_sysfs_remove_device_info() as
these functions is going to create more attributes rather than just the
link to the disk. No functional changes.
