Bitra (Realme GT Neo 2 5G) Kernel Builder: NoMount + SuSFS + APatch

This repository provides an automated GitHub Actions CI pipeline to build a monolithic Linux 4.19.157-perf+ kernel for the Realme GT Neo 2 5G (bitra / RMX3370, Snapdragon 870 SM8250) on Android 13 (Realme UI 4.0 / ColorOS 13.1).

Features Integrated

1. NoMount Built-in (CONFIG_NOMOUNT=y):
   • Zero-mount VFS hijacking with zero entries in /proc/self/mountinfo.
   • Zero-footprint Keyring IPC returning -ENOKEY to eliminate the detection oracle.
   • RCU-walk safety and memory barrier fixes for clean teardown.
2. SuSFS 4.19 (CONFIG_KSU_SUSFS=y):
   • Mount ID isolation & kernel kallsyms symbol filter (nm_*, nomount_*).
   • Concealment of root indicators, modules, and processes.
3. APatch Root Integration:
   • Kernel binary pre-patching via kptools with user-specified SuperKey.
   • Preserves root without tripping bootloader state checks.
4. AnyKernel3 Zip Packaging:
   • Automatically outputs AnyKernel3-NoMount-bitra.zip ready to flash via TWRP Recovery.

How to Build via GitHub Actions

1. Push this folder to a GitHub repository:

   git remote add origin https://github.com/<your-username>/<your-repo-name>.git
   git branch -M master
   git push -u origin master

2. In your GitHub repository, navigate to the Actions tab.
3. Select Build Bitra Kernel with NoMount, SuSFS & APatch.
4. Click Run workflow:
   • Enter your desired APatch SuperKey (default: AntigravityRoot).
   • Target branch: android-13.
5. Once compilation finishes (~10-15 minutes), download AnyKernel3-NoMount-bitra.zip from the workflow artifacts.
6. Reboot to TWRP Recovery on your Realme GT Neo 2 (sde26) and flash the zip.
