Hi,

depracated for quite some time. Attached you can find the patch to
handle this - see the patch description for more information.

Subject: use oom_score_adj rather than deprecated oom_adj
/proc/<pid>/oom_adj is on the way out from the kernel and
all users are supposed to use oom_score_adj instead.
The current BOINC_OOM_ADJ is using OOM_ADJUST_MAX which
corresponds to OOM_SCORE_ADJ_MAX.
