[LTP] [PATCH] lib: memutils: don't pollute entire system memory to avoid OoM

[Cyril Hrubis]

Hi!
I guess that this is another bug that should be fixed before the
release. I still think that the memory pollution is a best effort
operation and that we should be more conservative with the reserve. I
would go for a few percents of the free memory just to be extra sure
that we do not cause memory pressure.

If we go for 2% we will add following;

safety = MAX(safety, info.freeram / 50);

Also it looks like info.freeram is the same as MemFree: from
/proc/meminfo, I guess that this is not wrong, since memory that have
been used in buffers is dirty enough for our case.
