Message

So here's v3 which takes care of the feedback received in the last round, namely:

 - Introduced btrfs_exclop_balance which is used to switch the balance state,
 alongside ASSERTS
 - Removed unused variable in balance_kthread

Nikolay Borisov (3):
  btrfs: introduce BTRFS_EXCLOP_BALANCE_PAUSED exclusive state
  btrfs: make device add compatible with paused balance in
    btrfs_exclop_start_try_lock
  btrfs: allow device add if balance is paused

With the minor message fixup added to misc-next, thanks.
