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
