From: Harry Wei 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.
