36742cc17e feat: detect proc_ops support via header parsing instead of version check. (#411) 
Some kernels (e.g. 5.4 with backports) include proc_ops despite being
older than 5.6.0. Replace hardcoded version check with runtime header
detection to handle these cases.

- Check for "struct proc_ops" in include/linux/proc_fs.h
- Use KSU_COMPAT_HAS_PROC_OPS macro for conditional compilation
- Fixes build failures on kernels with backported proc_ops

2ab242a209 kernel: Remove unnecessary strip in CONFIG_KSU_TRACEPOINT_HOOK check (#353) 
The 'strip' function is redundant when checking Kconfig variables, as
values from CONFIG options (like CONFIG_KSU_TRACEPOINT_HOOK) are already
trimmed and do not contain leading/trailing whitespace.

Simplify the condition for better readability and maintainability:
  - Remove unnecessary $(strip ...)
  - Add consistent spacing around the comma

This change aligns with kernel Makefile conventions and improves code clarity
without altering behavior.

ff6a68221f kernel: add wrapper for creds, refine disable_seccomp, revert some changes (#131) 
1. Wrapper for creds:
* Some older kernel does not have {.val}, so, for nicer compatibility support and clean code,
make some wrapper for credential use.
* After this change, do not use current_uid().val, instead, use ksu_current_uid(). For more
info, check kernel/include/ksu_creds.h.

2. Refine disable_seccomp (need to add k6.11+ support)
https://github.com/tiann/KernelSU/pull/2708
https://github.com/tiann/KernelSU/issues/2706

3. Revert "Handle unmount for isolated process correctly"
Reason: https://github.com/tiann/KernelSU/pull/2696#issuecomment-3181866301

4. consolidate most of the gaps

68f2f5a0ae kernel: Introducing Tracepoint Hook Type Support 
Tracepoint is a predefined hook point in the kernel, compared to Kprobe,
it is more stable and has lower performance overhead, although compatibility
is relatively poor, it is still worth trying

By the way, we have also included the config definitions related to hook types
in Kconfig, to enhance cleanliness

Improve and merge types that do not require hooks

Introducing the hook type prctl

These patches is based on backslashxx/KernelSU#5

f1ba7127b8 kernel: refactor CMD_GET_FULL_VERSION to safely initialize version string (#220) 
Use strscpy()/strlcpy() to populate the version buffer in CMD_GET_FULL_VERSION
instead of relying on uninitialized memory. This ensures the returned string
is null-terminated and avoids exposing garbage data to user space.

b4cfc2f298 Suggest non-gki kernel users to backport path_umount (#1464) 
Most kernel builders have to touch their kernel source code anyway, why
not also tell them to backport path_umount so even non-gki users can
benefit from this?

I know this might be a bit controversial as this will raise the barrier
of entry, but the benefits are just so high.

Idea was from OnlyTomInSecond on KernelSU group chat way back, and it
has been on the discussions for some time

ofcourse having someone on 3.18 confirm this will be nice.

**PROS**: umount modules for everyone
**CONS**: barrier of entry +1
