This is why we also added them to UBIFS - good JFFS2 experience. Yeah, this is what the dbg_gen doing :-) But often we need messages from lower layers, why not? I agree we should lessen the amount of prints, but I still do not get it what is your argument against them the shiny prints which we may compile in when we want to debug :) Why? What is wrong with this? As I said, we found it very useful in JFFS2, because I has been working with JFFS2 for _long_ time. Talk to David Woodhouse and ask how many times that made him fix a bug just by having people send a log. Why do you want to prevent us from having this? This alternative is not really acceptable. We want to have only _few_ debugging things always enabled, and have other things always compiled out and compiled in only when hunting a problem. We can if we have to. But these checks often affect the FS behavior and sometimes make bugs go away and become unreproducible. Especially locking problems. This is why we want to be able to enabling them separately. -- Best Regards, Artem Bityutskiy (Артём Битюцкий) --
