Hi Vlastimil,
your commit 1434c81a47e3 ("mm, compaction: export tracepoints zone names
to userspace") has shown up in todays linux-next tree (i.e., 20150923)
adding the following lines of code:
--- a/include/trace/events/compaction.h
+++ b/include/trace/events/compaction.h
@@ -18,6 +18,31 @@
[...]
+#ifdef CONFIG_ZONE_HIGHMEM_
+#define IFDEF_ZONE_HIGHMEM(X) X
+#else
+#define IFDEF_ZONE_HIGHMEM(X)
+#endif
At the current state, the #ifdef block will not see a compiler since
CONFIG_ZONE_HIGHMEM_ is not defined anywhere. At first I thought it's a
typo as it ends with '_', but even ZONE_HIGHMEM isn't defined in
Kconfig. Is there a patch queued somewhere to fix the issue?
I detected the issue with undertaker-checkpatch from [1]. We run a bot
daily on linux-next to detect some Kconfig related issues and bugs.
Kind regards,
Valentin
