when we add a new disk to the mounted btrfs we don't record it
as of now, disk add is a critical change of btrfs configuration,
it must be recorded in the syslog to help offline investigations
of customer problems when reported.

Please use 'device' instead, I think we're moving away from 'disk'
everywhere else. Nitpick: space after the ,

Otherwise good,
