6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Slavin Liu [ Upstream commit c9e6e5f38bf75276605f1952b22285f5f3abcaff ] Stream assignment can fail when hardware streams are exhausted. Move the tracepoint after the NULL check because its payload accesses the assigned stream tag. Detected by static analysis and reviewed with AI-assisted source auditing.
