Build error on Ubuntu 24.04 (kernel 6.14.0-32): 'struct fd' has no member named 'file'

Hi,
Thanks for this useful project! I tried to build it on Ubuntu 24.04 with kernel 6.14.0-32 and gcc 13.3, but the build failed due to a struct layout change in newer kernels.

System Information
• OS: Ubuntu 24.04 (Noble)
• Kernel: 6.14.0-32-generic
• GCC: 13.3.0
• NVIDIA Driver: 580.82.07

Build Command
make

Error Log
src/mpu_syscall_hook.c: In function ‘get_rdev’:

I’ve done some compatibility work on kernel 6.14.0-33. Feel free to give it a try and maybe star this repo if you find it helpful.
