Received from Mark Salyzyn,
This little patch removes the ',cid)' container identification argument
from some of the functions. The argument is used in some cases as merely
a debug helper and thus not used, and in others, the value can be
quickly acquired from the scsi command in their single solitary use in
the procedure rather than wasting resources on passing the argument in
from above.
