Since iSER was converted to use the generic virt_boundary mechanism (which was called something else in 4.4), it didn't handle the case where a request is using up the full size of max_hw_segments, but not actually aligned to the virt boundary. This series sets the maximum segment size limit to fix this workload (xfs_repair is a good reproducer, btw). Should probably go into 4.4 and 4.5-stable. Changes since V1: - use min_not_zero - use SIZE_4K instead of PAGE_SIZE in iser -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
