6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Geliang Tang <geliang.tang@xxxxxxxx> commit 06848c0f341ee3f9226ed01e519c72e4d2b6f001 upstream. This patch adds a new helper get_info_value(), using 'sed' command to parse the value of the given item name in the line with the given keyword, to make chk_mptcp_info() and pedit_action_pkts() more readable. Also add another helper evts_get_info() to use get_info_value() to parse the output of 'pm_nl_ctl events' command, to make all the userspace pm selftests more readable, both in mptcp_join.sh and userspace_pm.sh.
