Complile error: not import "VFS_internal_I_am_really_a_filesystem_and_am_NOT_a_driver" namespace

System information

Kernel Version	rockchip kernel 5.10.110

OpenZFS Version	2.1.12

Describe the problem you're observing

When I try to compile ZFS with Rockchip Kernel 5.10, I encountered an error while using the './configure' command. Upon my investigation, I found that it uses the 'EXPORT_SYMBOL_NS' macro when exporting some functions like 'kernel_read', which causes ZFS compilation to fail. What should I do to successfully compile ZFS?

Describe how to reproduce the problem

Always. By the way, the kernel I used: rockchip-linux/kernel@d483eed

Include any warning/errors/backtraces from the system logs

configure error:

this is the error in build.log:
The error:

Think you'd get to go through and patch everywhere with a reference to any of those with a MODULE_IMPORT_NS(etc).

Thank you for your response! It sounds good that I patch the source file with a MODULE_IMPORT_NS.
Actually I'm a beginner, and I'd like to know what steps I should take to pass the configure check.
There are many "m4" macro files used for checks, is there a convenient way using MODULE_IMPORT_NS to make unified modifications?

See here radxa/kernel#54 (comment)

Rockchip BSP kernel is forked from Android Common Kernel, don't think ZFS would support the Android kernel any time soon.

Wow, I'll try. Thank you so much for your help!
