[PATCH v2 0/2] Device name and RCU string

[David Sterba <dsterba@suse.com>]

v2:
- drop patch adding RCU protection around update_dev_time(), there's a
  sleeping allocation inside; after revisiting the RCU requirements, I
  don't think it's needed and we can access the raw string (the same way
  it was done with rcu_string), the time update is called from scratch
  superblocks and after the ->dev_list hook is removed, so there's no
  chance it can be reached from device_list_add

After recent simplifications of the RCU usage in messages, this patchset
implements the RCU protection directly without the RCU string so this
API can be removed completely as we don't have nor plan anything else to
use it for.

David Sterba (2):
  btrfs: open code RCU for device name
  btrfs: remove struct rcu_string
