------------------------------------------------------ From: Suren Baghdasaryan surenb@google.com Subject: tools: fix atomic_set() definition to set the value correctly Date: Fri, 27 Dec 2024 14:22:20 -0800
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.
