From: David Sterba <dsterba@xxxxxxxx>
commit 3e1ad196385c65c1454aceab1226d9a4baca27d5 upstream.
The new state allowing device addition with paused balance is not
exported to user space so it can't recognize it and actually start the
operation.
Fixes: efc0e69c2fea ("btrfs: introduce exclusive operation BALANCE_PAUSED state")
CC: stable@xxxxxxxxxxxxxxx # 5.17
