    Bottom-half for drivers in Kernel 3.1/3.2

    Hi guys,

    I've been studying Kernel drivers to start to understand Linux more, the documentation I can find on the internet tells me that in 2.6 a debate was ongoing regards dropping tasklets in favour of workqueues or some other bottom-half interrupt mechanism but I've been unable to find any documentation relating to the conclusion of this discussion.

    Does anyone know if a consensus was formed and if there were any kernel changes to go with it?

    Many thanks

    Hi,

    Tasklets are now old stuff, workqueues is what you must use as BH.

    Are the use of softirqs or kernel threads still acceptable under appropriate situations?
