[B.A.T.M.A.N.] [PATCH] batman-adv: Convert kbuild version check to preprocessor check

Makefile.kbuild includes a relative unreadable check for a version number to decide if we should compile bat_printk.c to get out own print implementations. This can easily be replaced using a simpler preprocessor check as we know them from compat.h Signed-off-by: Sven Eckelmann &lt;sven.eckelmann(a)gmx.de&gt; --- batman-adv/Makefile.kbuild | 6 +++++- batman-adv/bat_printk.c | 6 ++++++ 2 files changed, 11 insertions(+), 1 deletions(-) diff --git a/batman-adv/Makefile.kbuild b/batman-adv/Makefile.kbuild index 14e3daa..40ca316 100644 --- a/batman-adv/Makefile.kbuild +++ b/batman-adv/Makefile.kbuild @@ -32,4 +32,8 @@ EXTRA_CFLAGS += -DREVISION_VERSION=\"$(REVISION)\" endif obj-m += batman-adv.o -batman-adv-y := main.o bat_debugfs.o bat_sysfs.o send.o routing.o soft-interface.o icmp_socket.o translation-table.o bitarray.o hash.o ring_buffer.o vis.o hard-interface.o aggregation.o originator.o gateway_common.o gateway_client.o unicast.o $(shell [ "2" -eq "$(VERSION)" ] 2>&- && [ "6" -eq "$(PATCHLEVEL)" ] 2>&- && [ "$(SUBLEVEL)" -le "28" ] 2>&- && echo bat_printk.o) +batman-adv-y := aggregation.o bat_debugfs.o bat_sysfs.o bitarray.o \ + gateway_client.o gateway_common.o hard-interface.o hash.o \ + icmp_socket.o main.o originator.o ring_buffer.o routing.o \ + send.o soft-interface.o translation-table.o unicast.o vis.o +batman-adv-y += bat_printk.o diff --git a/batman-adv/bat_printk.c b/batman-adv/bat_printk.c index 4fa3e18..6bbeb8b 100644 --- a/batman-adv/bat_printk.c +++ b/batman-adv/bat_printk.c @@ -1,3 +1,7 @@ +#include <linux/version.h> + +#if LINUX_VERSION_CODE < KERNEL_VERSION(2, 6, 29) + /* * linux/lib/vsprintf.c * @@ -935,3 +939,5 @@ int bat_snprintf(char *buf, size_t size, const char *fmt, ...) return i; } + +#endif /* < KERNEL_VERSION(2, 6, 29) */ -- 1.7.1
