by Wei Li 06 Jun '23

06 Jun '23

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I7BAJ0 -------------------------------- EulerFS was introduced as a technical preview feature in the 21.09 innovation version. Considering the current discontinuation of Intel Optane hardware and immature ecosystem, it has been decided to turn it off in the 22.03 LTS version. It will continue to evolve as an innovative feature in future innovation versions.

As suggested by Denis and Eric, TCP_REPAIR_OPTIONS should be prohibited if data was already sent. socket-tcp tests in CRIU has been tested as follows: $ sudo ./test/zdtm.py run -t zdtm/static/socket-tcp* --keep-going \ --ignore-taint socket-tcp* represent all socket-tcp tests in test/zdtm/static/.
