Should it be static? ``` The variable is defined at `panthor_drv.c:1830`: ```c bool panthor_transparent_hugepage =3D true; module_param_named(transparent_hugepage, panthor_transparent_hugepage, bool= , 0400); ``` It is used externally in `panthor_gem.c:25-26`, which already includes `pan= thor_drv.h` and uses the `extern` declaration there. The fix has two parts: 1. **Adding `#include ` to `panthor_drv.h`** =E2=80=94 Corre= ct. The header uses `bool` in `extern bool panthor_transparent_hugepage;` a= nd must be self-contained. Without this include, the header would break if = included in a translation unit that didn't already pull in a header definin= g `bool`. 2. **Adding `#include "panthor_drv.h"` to `panthor_drv.c`** =E2=80=94 Corre= ct. This is the standard kernel pattern: a `.c` file should include its own= header so the compiler can verify the definition matches the `extern` decl= aration. The include is placed in alphabetical order among the other `panth= or_*.h` includes, which is good. **Minor observations (not blocking):** - The commit message is terse ("Make it clean"). It would be slightly bette= r to say something like "Include panthor_drv.h from panthor_drv.c so the co= mpiler can verify the definition of panthor_transparent_hugepage matches it= s extern declaration." But for a trivial sparse fix, this is acceptable. - The header's copyright says "Copyright 2025 Amazon.com" =E2=80=94 this su= ggests the header was recently created (likely when the transparent hugepag= e support was added). The fact that `panthor_gem.c` already included it con= firms the header pre-dates this patch, and only the self-include from the d= efining file was missing. **No functional or correctness concerns.** --- Generated by Claude Code Patch Reviewer
