> Subject: [LTP] [PATCH] Set tunable value of min_free_kbytes lower
>
> From: Shuang Qiu <[email protected]>
>
> The value of min_free_kbytes is set too high(half of mem_free) during
> testing min_free_kbytes tunable.It often cause the system to become
> out-of-memory.Using 20% of mem_free to avoid oom and system hang.
Thanks for the patch, I will test the patch, will provide feedback ASAP.
