From f716d8303345698728d9f8ce76a82a795a5be275 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 6 Mar 2006 17:41:44 -0800 Subject: [PATCH] Allocate 96 bytes for SCSI sense data reply The SCSI layer uses SCSI_SENSE_BUFFERSIZE (96) for the sense buffer size, even though some other code uses "sizeof(struct request_sense)" (which is 64 bytes). Allocate the buffer using the bigger of the two for safety.
