| Series | selftests/nolibc: remove test gettimeofday_null | expand |
Hi, Willy
I plan to send the v3 of rv32 series, but this patch may conflict with:
selftests/nolibc: remove gettimeofday_bad1/2 completely [1]
If this is mergable, perhaps I should wait for your new
2023xxxx-nolibc-rv32+stkp6 ;-)
And I plan to add the gettimeofday_tv and gettimeofday_tv_tz in the new generic
part1.
selftests/nolibc: add new gettimeofday test cases [2]
Best regards,
Zhangjin

gettimeofday() is not guaranteed by posix to handle a NULL value as first argument gracefully. On glibc for example it crashes.
