lowmemorykiller: make default lowmemorykiller debug message useful
lowmemorykiller debug messages are inscrutable and mostly useful
for debugging the lowmemorykiller, not explaining why a process
was killed. Make the messages more useful by prefixing them
with "lowmemorykiller: " and explaining in more readable terms
what was killed, who it was killed for, and why it was killed.
The messages now look like:
[ 76.997631] lowmemorykiller: Killing 'droid.gallery3d' (2172), adj 1000,
[ 76.997635] to free 27436kB on behalf of 'kswapd0' (29) because
[ 76.997638] cache 122624kB is below limit 122880kB for oom_score_adj 1000
[ 76.997641] Free memory is -53356kB above reserved
A negative number for free memory above reserved means some of the
reserved memory has been used and is being regenerated by kswapd,
which is likely what called the shrinkers.
