From: Peng Li commit 056b93566a35 ("mm/vmalloc: warn only once when vmalloc detect invalid gfp flags") modify the function call from WARN to WARN_ONCE. WARN_ONCE input parameter format error, missing ',' tag. Resulting in the following compilation errors: mm/vmalloc.c:3940:19: error: expected ‘)’ before ‘invalid_mask’ 3940 | invalid_mask, &invalid_mask, flags, &flags); After adding the "," tag, the compilation passed.
