selftests/futex: Create test for robust list
Create a test for the robust list mechanism. Test the following uAPI
operations:
- Creating a robust mutex where the lock waiter is wake by the kernel
selftests/futex: Create test for robust list
Create a test for the robust list mechanism. Test the following uAPI
operations:
- Creating a robust mutex where the lock waiter is wake by the kernel
when the lock owner died
- Setting a robust list to the current task
- Getting a robust list from the current task
- Getting a robust list from another task
- Using the list_op_pending field from robust_list_head struct to test
robustness when the lock owner dies before completing the locking
- Setting a invalid size for syscall argument `len`
- Adding multiple elements to a robust list wait waiting for each of
them
- Creating a circular list and checking that the kernel does not get
stuck in an infinity loop
