Here is a fancy fix to Magisk for android-10 on potter,
Problem is actually in the kernel (dont be happy as this needs to be fixed), and somehow on the EAS kernels it works fine.

(tnxto: GtrCraft for OPD EAS, Potato guy for hints over to possible issues/ standalone eas kernel workaround, Shivv for trying it out and vinyas to test in arrow-10.0)

test:
flash this kernel and magisk on already booted arrow-10.0 or anyother android-10.0
note:
- wip, totally upto user to try. There may be unknown issues.
