Two things:

1. did this kernel pass the boot test?
2. the Legacy branch of KernelSU Next doesn't support SuSFS, and I, as an upstream(NonGKI_Kernel_Build_2nd), don't introduce KernelSU Fork's Fork unless it's for maintenance considerations.

Yes, it passes the boot test without SUSFS (KernelSU Next legacy works fine).

I also tested with Sukisu Ultra (builtin):

· When SUSFS is enabled in defconfig, it says "no driver found"
· When SUSFS is disabled in defconfig, Sukisu Ultra works fine

Fixing SukiSU Ultra Build Errors on Kernel 4.14

I Encountered a Build Problem

I encountered a problem building the kernel with SukiSU Ultra (builtin) on Xiaomi Redmi Note 7 Pro (violet) - Kernel 4.14.

---

The Problem

When trying to build, I got two linker errors:

First Error:

ld.lld: error: undefined symbol: ksu_vfs_read_hook
>>> referenced by read_write.c:583

Second Error:

ld.lld: error: undefined symbol: sys_move_mount
>>> referenced by sys32.c:49
>>> referenced by sys.c:62

---

How to Fix the Problem

Fix for First Error: ksu_vfs_read_hook

First File: KernelSU/kernel/ksu.h

I added before the last line (#endif):

#if defined(CONFIG_KSU_MANUAL_HOOK) || defined(CONFIG_KSU_SUSFS)
extern bool ksu_vfs_read_hook;
#endif

Second File: KernelSU/kernel/ksud.c

I added at line 86 (after ksu_execveat_hook):

bool ksu_vfs_read_hook __read_mostly = true;

---

Fix for Second Error: sys_move_mount

File: arch/arm64/kernel/sys.c

I added after the arm64_personality function:

asmlinkage long sys_move_mount(int from_dfd, const char __user *from_pathname,
			       int to_dfd, const char __user *to_pathname,
			       unsigned int flags)
{
	return -ENOSYS;
}

⚠️ Important Note: Do NOT modify sys32.c - modifying only sys.c is enough!

---

Result

✅ Problem solved successfully!

After the modifications, the build completed without errors:

CC      fs/read_write.o
CC      arch/arm64/kernel/sys.o

LD      vmlinux
GZIP    arch/arm64/boot/Image.gz

Image.gz created ✓

Summary of Changes

File	Modification
KernelSU/kernel/ksu.h	Add extern declaration
KernelSU/kernel/ksud.c	Add variable definition
arch/arm64/kernel/sys.c	Add stub function

Total files modified: 3 files only

Problem solved thanks to Claude AI

• Device: Xiaomi Redmi Note 7 Pro (violet)
• Kernel: 4.14.x
• SukiSU: SukiSU Ultra v4.1.1 (builtin)
• Status: ✅ Working successfully

I also tested with Sukisu Ultra (builtin):

· When SUSFS is enabled in defconfig, it says "no driver found"
· When SUSFS is disabled in defconfig, Sukisu Ultra works fine

SukiSu builtin branch doesn't support SuSFS also.
Here is message from Rifsxd about KSUN legacy branch

Ksun v3.0.1 legacy branch now should be stable enough for daily use, and since I've got my legacy 4.14 device unlocked so now on I can personally test and keep legacy branch updated and maintained.

The kernel has the following compilation error which relates to the SuSFS AVC LOG function, the cause of the compilation error is unknown, and I've been troubleshooting for a long time without finding a solution.
So assuming you still want me to maintain the kernel, you'll have to opt out of SuSFS.
