Hi Cyril,
I also wondered whether to add these two testcases into futex_waitv01.c, there is a consideration that there are alse two other testcases need to be added according to linux manual:
1. A signal was sent to the sleeping task, returning -ERESTARTSYS.
2. Some futex at the list was woken, returning the index of some waked futex.
Best wishes!
Gongyi

Will you send a patch that adds these cases to the futext_waitv01.c
then?

Feel free to send more patches, adding more test coverage is always
welcomed.

Hi Cyril,
I have resubmit the patch that move the test code to futex_waitv01.c as your suggestion, please see: https://patchwork.ozlabs.org/project/ltp/patch/20220607025435.184105-1-zhaogongyi@huawei.com/
Best wishes,

EAGAIN
Is there a reason why can't we add these two testcases into
futex_waitv01.c?

Add test verifies EAGIN/ETIMEDOUT for futex_waitv according to
https://www.kernel.org/doc/html/latest/userspace-api/futex2.html.
