    I wrote in the commit logs, that the functions are only used as argument
    to __{dev,}exit_p. There are no direct calls. (IIRC there was only one
    exception that I checked manually.)

    I think the __{dev,}exit_p wrappers are only used to define remove
    callbacks, so there should be no harm.

    Best regards and thanks for your feedback,
