Date: Sat, 26 Sep 2009 21:27:48 +0200 From: Samuel Thibault <samuel.thibault@...-lyon.org> To: linux-kernel@...r.kernel.org Subject: [PATCH,TRIVIAL] Fix csum_ipv6_magic asm memory clobber Just like ip_fast_csum, the assembly snippet in csum_ipv6_magic needs a memory clobber, as it is only passed the address of the buffer, not a memory reference to the buffer itself.
