(The poison would indicate that the elements p->dfs_link points to are freed, not p itself.) If you could run with lockdep (to verify that the locks are indeed held here) and kasan to find the alloc/free of the struct being used-after-free, that would be extremely valuable. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
