Bottomley" , "Martin K. Petersen" , Michael Schmitz , linux-m68k@vger.kernel.org, linux-scsi@vger.kernel.org, linux-kernel@vger.kernel.org Cc: Ondrej Zary , Sam Creasey List-Id: linux-m68k@vger.kernel.org The driver has a limit of eight LUs because of the byte-sized bitfield that is used for busy flags. That means the maximum LUN is 7. The default is 8.
