Hi, I saw a weird behavior, a "#if 0" isn't expanded as it should be, the code isn't grayed is it a bug? Here is the file where I found this behavior: https://github.com/codekipper/linux-sunxi/blob/audio_mainlining/sound/s oc/sunxi/sunxi-i2s.c#L236 I tried on other files, I get the same behavior. Best regards, Alexis.
