6.9-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 6a85e34c4d07d2ec0c153067baff338ac0db55ca ]
Make it match its definition (size_t vs unsigned long). And declare it in a shared header to fix the -Wmissing-prototypes warning, as it is defined in the user code and called in the kernel code.
