    You don't want to do that :) You're starving other GFP_ATOMIC
    processes, and will increase system failures due to lack of memory...
    even though there may be plenty outside the emergency pools.

    One option is to create a background kernel thread (via schedule_task or
    schedule_work, depending on your kernel version) that allocates memory
    which your tasklet then takes.
