(replying to an e-mail of three months ago) Hello Dan, While building a v4.12 kernel I noticed that enabling device mapper support now unconditionally enables DAX. I think there are plenty of systems that u= se dm but do not need DAX. Have you considered to rework this such that instea= d of dm selecting DAX that DAX support is only enabled in dm if CONFIG_DAX is enabled? Thanks, Bart.
