after upgrading to 17.01.02 I have some kernel warnings regarding f2fs at bootup.
Such warnings are already mentioned in a posting in the developer forum and there is also already a bugreport.
I am not sure about these warnings, should I worry about them (and go back)?
Or these warnings are "only" warnings and not errors, as usual?
Router is a wr1043nd v1 with extroot configuration, image has been created with imagebuilder 17.01.02 with f2fs like described in extroot docu.
