Subject: doc, mm: clarify /proc/<pid>/oom_score value range
X-Git-Tag: v5.10.7~1862^2~141
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b1aa7c9377bdff904efa0fbde1f96e1769730d8a;p=platform%2Fkernel%2Flinux-rpi.git

doc, mm: clarify /proc/<pid>/oom_score value range

The exported value includes oom_score_adj so the range is no [0, 1000] as
described in the previous section but rather [0, 2000].  Mention that fact
explicitly.
