kernel: expose allowlist workaround as Kconfig option
...
Useful for situations where the SU allowlist is not kept after a reboot.
As per upstream this is only used for < 4.10 and Huawei HiSilicon devices.
but theres user reports having issues even on 4.14/4.19 samsung kernels.
Expose this option so users affected can opt-in.

kernel: require path_umount backporting
...
Most kernel builders have to touch their kernel source code anyway so
we might as well tell them to backport path_umount to achieve some sort
of feature parity.
This enforces a path_umount backport, not a suggestion.
Its a requirement from now on.
You will backport path_umount and you will like it.

kernel: Relax dentry_path_raw compare in core_hook ( #2041 )
...
On Android-x86 (or BlissOS) it initialize Android by using switch_root
or chroot, when checking a path with dentry_path_raw() it will show the
whole real path instead of the path that we want.
Relax the checking requirement by using strstr to look for
"/system/packages.list" in the string instead of requiring the path to
be "/system/packages.list"
This fixes #1783

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
