No, I havn't - I submitted this patch already several years ago, but
it was never merged, and since then, I've been carrying this patch
around in all kernels I ever used. While doing some other kernel work
this week, I decided to resubmit it, because I thought it's a security
vulnerability to ignore the umask. But thanks, it's a good hint, I'll
check that 2022 commit.
