[PATCH] Fix bad data direction in SG_IO
Contrary to what the name misleads you to believe, SG_DXFER_TO_FROM_DEV is really just a normal read seen from the device side. This patch fixes http://lkml.org/lkml/2006/10/13/100 Signed-off-by: Jens Axboe <jens.axboe@oracle.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
