[PATCH] ide-scsi: kmap scatter/gather before doing PIO From: Stuart Hayes <Stuart_Hayes@dell.com> The system can panic with a null pointer dereference using ide-scsi if PIO is being done on scatter gather pages that are in high memory, because page_address() returns 0. We are actually seeing this using a tape drive. This patch will kmap_atomic() the pages before performing PIO. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@elka.pw.edu.pl>
