    Alan,

    On a related subject, a few months ago you posted a patch which added a
    nice add_timeout()/timeout_pending() API and converted many (if not
    most) drivers to use it.

    If I remember correctly it did not generate much comments and the work
    was not pushed into mainline.

    I think it's a nice cleanup, IMHO the time_(before|after)(jiffies, ...)
    construct is horrible.

    Any chance to resurrect this work ?

    PS: the original subject was "Initial bits to help pull jiffies out of
    drivers"

    Best regards,

    Eric St-Laurent
