If it is a fix, then I would suggest targeting it at 'nf' and providing a Fixes tag. The above notwithstanding, this looks good to me.

Thanks, I'm confused about when to use "nf-next" or "net" or "net-next". "nf-next" means fixing errors for linux-next.git and linux-stable.git, while "nf" or "next" just means linux-next.git? > > If it is a fix, then I would suggest targeting it at 'nf' > and providing a Fixes tag.

Hi Kunwu, nf is for fixes for Netfilter (which includes IPVS). The target tree is nf.git nf-next is for non-fixes for Netfilter. The target tree if nf-next.git net is for fixes for Networking code, which does not have a more specific tree (as is the case for Netfilter). The target tree is net.git. Liikewise, net-next is for non-fixes for Networking code. The target tree is net-next.git The MAINTAINERS file, and get_maintainers.pl script are useful here. nf is merged into net on request from the Netfilter maintainers, this is it's path to released kernels. Likewise, nf-next is merged into net-next. > > > > > If it is a fix, then I would suggest targeting it at 'nf' > > and providing a Fixes tag. > I'll keep it in mind in the future. > > > > The above notwithstanding, this looks good to me. > > > > Acked-by: Simon Horman <horms@kernel.org> > > > > > --- > > > net/netfilter/ipvs/ip_vs_conn.c | 4 +--- > > > 1 file changed, 1 insertion(+), 3 deletions(-) > > > > > > diff --git a/net/netfilter/ipvs/ip_vs_conn.c b/net/netfilter/ipvs/ip_vs_conn.c > > > index a743db073887..98d7dbe3d787 100644 > > > --- a/net/netfilter/ipvs/ip_vs_conn.c > > > +++ b/net/netfilter/ipvs/ip_vs_conn.c > > > @@ -1511,9 +1511,7 @@ int __init ip_vs_conn_init(void) > > > return -ENOMEM; > > > /* Allocate ip_vs_conn slab cache */ > > > - ip_vs_conn_cachep = kmem_cache_create("ip_vs_conn", > > > - sizeof(struct ip_vs_conn), 0, > > > - SLAB_HWCACHE_ALIGN, NULL); > > > + ip_vs_conn_cachep = KMEM_CACHE(ip_vs_conn, SLAB_HWCACHE_ALIGN); > > > if (!ip_vs_conn_cachep) { > > > kvfree(ip_vs_conn_tab); > > > return -ENOMEM; > -- > Thanks, > Kunwu > ^ permalink raw reply [flat|nested] 6+ messages in thread
