Date: Sun, 30 Dec 2012 22:42:51 +0100 (CET) From: Jesper Juhl <jj@...osbits.net> To: linux-kernel@...r.kernel.org cc: Eric Dumazet <edumazet@...gle.com>, Al Viro <viro@...iv.linux.org.uk>, Dan Carpenter <dan.carpenter@...cle.com>, Jens Axboe <axboe@...nel.dk> Subject: [PATCH] relay: use sizeof(size_t), not sizeof(size_t *) in relay_create_buf() A number of size_t's is what we want to allocate memory for, not a number of size_t pointers (at least as far as I can tell). Now, depending on platform, sizeof(size_t *) may be >= sizeof(size_t) so things actually work, but that's not really a portable assumption, so let's use the value we actually mean.
