Subject: [PATCH] Shrink struct task_struct::oomkilladj
oomkilladj is 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.
