Describe the bug

I am build 5.4 kernel with sukiSU by tmp-builtin branch, everything is working good until i try to add SUSFS patch from https://gitlab.com/simonpunk/susfs4ksu/-/tree/kernel-5.4 on it.

Just found that there was some per-patched code on sukiSU kernel, but those are not suitable for non-gki, and causing below error pop up when building kernel:

/home/upc/android/mi11-kernelsukiSU410-susfs/common/drivers/kernelsu/supercalls.c:990:16: error: use of undeclared identifier 'SUSFS_MAGIC'

Can you reverse those code to offical KernelSU so i can patch it by myself, or update the code for non-gki so we can add SUSFS? thanks.

To Reproduce

  1. build bootable 5.4 kernel with sukiSU
  2. add SUSFS patch from https://gitlab.com/simonpunk/susfs4ksu/-/tree/kernel-5.4 on it
  3. build error pop up

Expected behavior

Manually patch SUSFS code and able to build kernel
