Subject: selftests/mm: fix awk usage in charge_reserved_hugetlb.sh and hugetlb_reparenting_test.sh that may cause error
Date: Wed, 27 Sep 2023 02:19:44 +0800
According to the awk manual, the -e option does not need to be specified
in front of 'program' (unless you need to mix program-file).
The redundant -e option can cause error when users use awk tools other
than gawk (for example, mawk does not support the -e option).
Error Example:
awk: not an option: -e
