Date: Sun, 26 Nov 2006 12:26:08 -0800 From: Roland Dreier <rdreier@...co.com> To: Linus Torvalds <torvalds@...l.org> Cc: Andrew Morton <akpm@...l.org>, David Miller <davem@...emloft.net>, linux-kernel@...r.kernel.org, openib-general@...nib.org, tom@...ngridcomputing.com, Al Viro <viro@...iv.linux.org.uk> Subject: Re: [PATCH] Avoid truncating to 'long' in ALIGN() macro > +#define ALIGN(x,a) __ALIGN_MASK(x,(typeof(x))(a)-1) > +#define __ALIGN_MASK(x,mask) (((x)+(mask))&~(mask)) Fine by me, but it loses the extra (typeof(x)) cast that Al wanted to make sure that the result of ALIGN() is not wider than x. - R. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
