Each gains the minimal two-line header in the area's existing form: 'SPDX-License-Identifier: BSD-3-Clause' plus 'Copyright (c) 2026 Open-IOV contributors'; shebang and coding lines stay first. No other content touched. kernel/** is deliberately out of scope (recorded as a follow-up in CODESTD-REPORT-2026-10-08.md): its SPDX coverage and MODULE_LICENSE normalization need their own GPL-2.0 pass. guest-diag: per-thread kernel stack sampler for the CUDA client 2026-09-29T20:57:09+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-09-29T20:57:09+00:00 urn:sha1:50da0edc952f5ad93dcbd33a3e5cb974d2411d45 The failing wait can live in a libcuda worker thread (strace without -f misses it); sample every /proc/<pid>/task/*/stack + wchan while the client runs.
