From: Andrey Konovalov <andreyknvl@xxxxxxxxxx> A few fixes for the stack depot eviction series. Changes v2->v3: - Use raw spinlock instead of spinlock to avoid issues on RT kernels. Changes v1->v2: - Add Fixes tags. - Use per-object spinlock for protecting aux stack handles instead of a global one.
