From 405f55712dfe464b3240d7816cc4fe4174831be2 Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Sat, 11 Jul 2009 22:08:37 +0400 Subject: headers: smp_lock.h redux * Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Signed-off-by: Alexey Dobriyan Signed-off-by: Linus Torvalds --- net/appletalk/ddp.c | 1 + net/ipx/af_ipx.c | 1 + net/irda/af_irda.c | 1 + net/irda/irnet/irnet.h | 1 - net/irda/irnet/irnet_ppp.c | 1 + net/sunrpc/clnt.c | 1 - net/sunrpc/sched.c | 1 - net/sunrpc/svc_xprt.c | 1 + net/wanrouter/wanmain.c | 1 + net/x25/af_x25.c | 1 + 10 files changed, 7 insertions(+), 3 deletions(-) (limited to 'net') diff --git a/net/appletalk/ddp.c b/net/appletalk/ddp.c index 590b8396362..bfbe13786bb 100644 --- a/net/appletalk/ddp.c +++ b/net/appletalk/ddp.c @@ -54,6 +54,7 @@ #include #include #include +#include #include /* For TIOCOUTQ/INQ */ #include #include diff --git a/net/ipx/af_ipx.c b/net/ipx/af_ipx.c index 417b0e30949..f1118d92a19 100644 --- a/net/ipx/af_ipx.c +++ b/net/ipx/af_ipx.c @@ -41,6 +41,7 @@ #include #include #include +#include #include #include #include diff --git a/net/irda/af_irda.c b/net/irda/af_irda.c index cb762c8723e..80cf29aae09 100644 --- a/net/irda/af_irda.c +++ b/net/irda/af_irda.c @@ -45,6 +45,7 @@ #include #include #include +#include #include #include #include diff --git a/net/irda/irnet/irnet.h b/net/irda/irnet/irnet.h index bccf4d0059f..b001c361ad3 100644 --- a/net/irda/irnet/irnet.h +++ b/net/irda/irnet/irnet.h @@ -241,7 +241,6 @@ #include #include -#include #include #include #include diff --git a/net/irda/irnet/irnet_ppp.c b/net/irda/irnet/irnet_ppp.c index 6d8ae03c14f..68cbcb19cbd 100644 --- a/net/irda/irnet/irnet_ppp.c +++ b/net/irda/irnet/irnet_ppp.c @@ -13,6 +13,7 @@ * 2) as a control channel (write commands, read events) */ +#include #include "irnet_ppp.h" /* Private header */ /* Please put other headers in irnet.h - Thanks */ diff --git a/net/sunrpc/clnt.c b/net/sunrpc/clnt.c index 5bc2f45bddf..ebfcf9b8990 100644 --- a/net/sunrpc/clnt.c +++ b/net/sunrpc/clnt.c @@ -28,7 +28,6 @@ #include #include #include -#include #include #include #include diff --git a/net/sunrpc/sched.c b/net/sunrpc/sched.c index 1102ce1251f..8f459abe97c 100644 --- a/net/sunrpc/sched.c +++ b/net/sunrpc/sched.c @@ -16,7 +16,6 @@ #include #include #include -#include #include #include diff --git a/net/sunrpc/svc_xprt.c b/net/sunrpc/svc_xprt.c index 6f33d33cc06..27d44332f01 100644 --- a/net/sunrpc/svc_xprt.c +++ b/net/sunrpc/svc_xprt.c @@ -5,6 +5,7 @@ */ #include +#include #include #include #include diff --git a/net/wanrouter/wanmain.c b/net/wanrouter/wanmain.c index 466e2d22d25..258daa80ad9 100644 --- a/net/wanrouter/wanmain.c +++ b/net/wanrouter/wanmain.c @@ -48,6 +48,7 @@ #include #include /* support for loadable modules */ #include /* kmalloc(), kfree() */ +#include #include #include /* inline mem*, str* functions */ diff --git a/net/x25/af_x25.c b/net/x25/af_x25.c index 21cdc872004..5e6c072c64d 100644 --- a/net/x25/af_x25.c +++ b/net/x25/af_x25.c @@ -40,6 +40,7 @@ #include #include #include +#include #include #include #include -- cgit v1.2.3 From a17d1720aa35623a9bef3707b36242706714bca5 Mon Sep 17 00:00:00 2001 From: Abhishek Kulkarni Date: Tue, 14 Jul 2009 13:24:10 -0500 Subject: 9p: default 9p transport module fix The default 9p transport module is not chosen unless an option parameter (any) is passed to mount, which thus returns a ENOPROTOSUPPORT.

This can be larger than what the page allocator can provide so it prints a warning. However, the caller is able to handle the situation so this patch suppresses the warning.
