Subject: [PATCH] Fix incorrect pointer in megaraid.c MODE_SENSE emulation
Date: Wed, 07 Dec 2005 17:46:57 -0500 [thread overview]
Message-ID: <43976661.1030004@rtr.ca> (raw)
[-- Attachment #1: Type: text/plain, Size: 190 bytes --]
The SCSI megaraid drive goes to great effort to kmap
the scatterlist buffer (if used), but then uses the
wrong pointer when copying to it afterward.
