    [PATCH] cpuset: remove test for null cpuset from alloc code path · c417f024
    Paul Jackson authored
    Remove a couple of more lines of code from the cpuset hooks in the page
    allocation code path.
    There was a check for a NULL cpuset pointer in the routine
    cpuset_update_task_memory_state() that was only needed during system boot,
    after the memory subsystem was initialized, before the cpuset subsystem was
    initialized, to catch a NULL task->cpuset pointer.
    Add a cpuset_init_early() routine, just before the mem_init() call in
    init/main.c, that sets up just enough of the init tasks cpuset structure to
    render cpuset_update_task_memory_state() calls harmless.
