[LTP] memcg_usage_in_bytes sometimes failed

[Hoang Nguyen]

Hi Cyril,
memcg_usage_in_bytes_test.sh is not changed for long time, so I think I almost used the latest version of LTP
I resend the log, some EOL issue when I send it with my phone. Sorry for inconvenience.

Hi!

First of all, which LTP version are you using?

Also please resend the log so that the text is not on a single line.
It's nearly impossible to read it as it is.
