 Hi Anshuman,
 
 Thanks for getting these testcases into the kernel.
 
 This patch adds a test to verify that the changed DSCR value inside
 any process would be inherited to it's child process across the fork
 system call.
 
 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.

Will save/restore the system DSCR default before exiting.

 
 Also a tiny nit, no need for a newline in perror():
 
 open() failed
 : Permission denied
 

sure, will remove them.

 With those changes you can add:

 to the patches based on my testcases.

Thanks.
