CVE-2025-68329 tracing: Fix WARN_ON in tracing_buffers_mmap_close for split VMAs

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix WARNON in tracingbuffersmmapclose for split VMAs When a VMA is split e.g., by partial munmap or MAPFIXED, the kernel calls vmops-close on each portion. For trace buffer mappings, this results in ringbufferunmap being...
