Seems like someone's been making some cosmetic tweaks to `include/linux/sysctl.h`. I see they've changed a kernel-doc comment (`/*`) to a standard C comment (`/`) and they've also fiddled with the formatting within the comment for `struct ctl_table_header`. Nothing major, just some style adjustments. Looking closely, I can confirm there are absolutely no functional changes to the code itself. Given that, there's no way this merits fuzzing; it's purely a documentation and formatting change. Therefore, I'm going to set `WorthFuzzing=false`. Next.

**Minor Sysctl.h Modification - WorthFuzzing=False**

Okay, so I've just reviewed this patch and it's pretty straightforward. Seems like someone's been making some cosmetic tweaks to `include/linux/sysctl.h`. I see they've changed a kernel-doc comment (`/**`) to a standard C comment (`/*`) and they've also fiddled with the formatting within the comment for `struct ctl_table_header`. Nothing major, just some style adjustments. Looking closely, I can confirm there are absolutely no functional changes to the code itself.
