6.12-stable review patch. If anyone has any objections, please let me know.

commit 4bbb6df62c54e6a2c1fcce4908df768f0cfa1e91 upstream.
Currently vma test is failing because of the new vma_assert_attached() assertion. The check is failing because previous refcount_set() inside vma_mark_attached() is a NoOp. Fix the definition of atomic_set() to correctly set the value of the atomic.
