[PATCH] Fix option_ms regression in 2.6.31-rc2

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Commit 32ebbe7b6ad44ae9c276419710b56de6ba705303 which filters the
SCSI REZERO command in option_ms based on a SCSI INQUIRY with a vendor
of Option breaks my Option Icon 225 (0af0:6971). This device returns a
vendor of ZCOPTION for the ZeroCD device. The following trivial patch
fixes things for me.
