Subject: [SCSI] scsi_debug: disable clustering
X-Git-Tag: v2.6.25-rc3~69^2~19
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cbccc207128e8bbdb047f6c5fc261acf207749c1;p=platform%2Fkernel%2Flinux-stable.git

[SCSI] scsi_debug: disable clustering

scsi_debug does at several places:

for_each_sg(sdb->table.sgl, sg, sdb->table.nents, k) {
	kaddr = (unsigned char *)
		kmap_atomic(sg_page(sg), KM_USER0);

We cannot do something like that with the clustering enabled (or we
can use scsi_kmap_atomic_sg).
