Hi all, After merging the final tree, today's linux-next build (powerpc allyesconfig) failed like this: net/netlink/af_netlink.c: In function 'netlink_frame_flush_dcache': net/netlink/af_netlink.c:384:40: error: 'NL_MMAP_MSG_HDRLEN' undeclared (first use in this function) Caused by commit 9652e931e73b ("netlink: add mmap'ed netlink helper functions"). This needed to be build tested on an architecture that has ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE set to 1 (like Sparc :-)). I added the following patch for today: From: Stephen Rothwell Date: Tue, 23 Apr 2013 17:40:35 +1000 Subject: [PATCH] netlink: fix typo in net/netlink/af_netlink.c Signed-off-by: Stephen Rothwell --- net/netlink/af_netlink.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/net/netlink/af_netlink.c b/net/netlink/af_netlink.c index 2a3e9ba..da5601d 100644 --- a/net/netlink/af_netlink.c +++ b/net/netlink/af_netlink.c @@ -381,7 +381,7 @@ static void netlink_frame_flush_dcache(const struct nl_mmap_hdr *hdr) /* First page is flushed through netlink_{get,set}_status */ p_start = pgvec_to_page(hdr + PAGE_SIZE); - p_end = pgvec_to_page((void *)hdr + NL_MMAP_MSG_HDRLEN + hdr->nm_len - 1); + p_end = pgvec_to_page((void *)hdr + NL_MMAP_HDRLEN + hdr->nm_len - 1); while (p_start <= p_end) { flush_dcache_page(p_start); p_start++; -- 1.8.1 -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
