I am currently modifying the Linux kernel (mainly in /mm) to gather memory related data in kernel.

Due to the large amount of data (maybe >500MB) and insufficient space allocated by kmalloc(), the user process was killed.

I originally used /proc and kernel module to read variables defined in the Linux kernel source code.

But now I want to transfer this data to user space so that I can store this large amount of data in its entirety. I don’t know what method to use?
