RFC:include/trace/events/btrfs.h

From: Harry Wei <[email protected]>

When i compile 2.6.39.1, it shows something wrong like below. When i open the file include/trace/events/btrfs.h i don't know how to fix these oops. They just give the entry of the function. So i can't get the exact line of the warnings. Can anyone give me some suggestions?

Thanks in advance.

Yeah, those line numbers (below) don't help very much.

There is a patch pending to fix these warnings. It's from
