Hi Yang,

I downloaded the development version of ltp two weeks ago, ran the cases in the runtest directory, and analyzed all the failed cases.
I found that these 3 cases have the umask issue.

Due to the limited time invested by individuals, it is possible that other cases with the same issue will not be discovered.
I will analyze the other failed cases that have not been concluded further in the next few weeks.

Thanks for your suggestions and reviews.

Best Regards
Zou Wei

Hi Zou,

Thanks for your patch set.
Did you find any other cases related with the same issue?

Thanks,
