 Subject: [LTP] memcg_stress on swap off system.
   
Hi LTP team,
I have this testcase run on my swap off system, and seem that the OOM restart it
I'm not sure I understand the entirely purpose of the testcase.But it seems the testcases try to allocate all free memory remain on the system,keep it for a while, then the main process send the signal to kill child process
   mem=$(( $mem_free + $swap_free / 2 ))   mem=$(( mem / 1024 ))
In case we have no swap_free, all memory is allocated, and trigger the OOM.I've still concerned which should be correct appoarch on swap-off system ? (set panic_on_oom=0 to avoid restaring Or the testcase shouldcheck if swap_free = 0, then we margin 10% of the final $mem ?)
(actullay pass/fail metric of this testcase is not so clear with me)
Could anyone give me some hints ?
Thanks a lot in advance
Hoang
