[Yang Xu]

HI!

This patchset is based on my previous msgrcv cleanup patch.
https://patchwork.ozlabs.org/project/ltp/patch/1594962618-26004-1-git-send-email-xuyang2018.jy@cn.fujitsu.com/

> 1. The first patch add check for msg_lrpid and msg_rtime.
> 2. The second patch tests different msgtyp.
> 3. The third patch tests MSG_COPY flag(basic error test),not functional
> test because kernel selftest[1] has tested this.
