From: Alexey Dobriyan Date: Wed, 17 Oct 2007 06:27:14 +0000 (-0700) Subject: Shrink struct task_struct::oomkilladj X-Git-Tag: v2.6.24-rc1~686 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3befe7ceb8d39a56a9ea55dd2da8b4bd9ddcdd36;p=linux-2.6 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.
