But if you go this far, an implement the anchor things, then it makes much more sense to implement your UBI2 ides, instead of this crippled "dump everything to flash on unmount" stuff. Your idea of a journal is much saner. Remember you suggested it to Samsung people as a way to fix mount time problems, but not memory consumption issuse, which are not that bad, and then you said we can create UBI3 to fix memory issues. -- Best Regards, Artem Bityutskiy (Артём Битюцкий)
