I know it is deprecated, but your change, staging: android,
lowmemorykiller: convert to use oom_score_adj, broke existing
user-space code that still write to /proc/pid/oom_adj. This option
lets you build a kernel that supports our user-space code until that
user-space has been converted to use /proc/pid/oom_score_adj.
