Root Cause:
Starting v6.15, vm_flags_set is marked GPL only symbol - torvalds/linux@45ad9f5
The build failed because dummy test module used a GPL‑only kernel symbol (__vma_start_write, reached via vm_flags_set) while declaring a non‑GPL license (MODULE_LICENSE("MIT")) in test_gdrdrv_HAVE_VM_FLAGS_SET.sh script. The kernel’s modpost step checks module license and rejected any module that uses GPL‑only symbols but is not marked with a GPL‑compatible license, which caused the error GPL-incompatible module test-dummy.ko uses GPL-only symbol '__vma_start_write' and a non‑zero return code.
Solution: Mark test-dummy.ko with Dual MIT/GPL license
