scsi_device::single_lun name change

[Douglas Gilbert <dougg@torque.net>]

While looking at struct scsi_target in a recent lk 2.6
kernel I was confused by this sentence:

"scsi_target: representation of a scsi target, for now,
  this is only used for single_lun devices." This is just above
the definition of the scsi_target structure in scsi_device.h

Elsewhere in that file scsi_device::single_lun is defined
with this comment:
"Indicates we should only allow I/O to one of the luns for
  the device at a time."
That implies that the target must have multiple lus when
single_lun is set :-)

Is it too late to rename that field to something like:
    serialize_lu_io  or single_lu_io ?
