These are lines where lint had suspected potential * improper alignment of a data structure; in each such situation * we have relied on the kernel guaranteeing proper alignment. * 2. Some 'for' loops have been commented as "'for' loop 1", etc * because they have 'continue' or 'break' statements in their * bodies.
