| |
oomkilladj in int, but values which can be assigned to it are -17, [-16, 15], thus fitting into s8.
While patch itself doesn't help in making task_struct smaller, because of natural alignment of ->link_count, it will make picture clearer wrt futher task_struct reduction patches. My plan is to move ->fpu_counter and ->oomkilladj after ->ioprio filling hole on i386 and x86_64. But that's for later, because bloated distro configs need looking at as well.
