Re: [PATCH V3 09/13] selftests, powerpc: Add test for DSCR value inheritence across fork

Hi Anshuman,

Thanks for getting these testcases into the kernel.

One issue I do notice (a bug in my original test cases too), is that we
don't restore the DSCR on exit. I'm not sure we need to go to the
trouble of saving and restoring it, but we should at least get it back
to 0 when done.

Also a tiny nit, no need for a newline in perror():

open() failed
: Permission denied

With those changes you can add:

to the patches based on my testcases.
