Steps to reproduce:
-----------------------------
# TuxMake is a command line tool and Python library that provides
# portable and repeatable Linux kernel builds across a variety of
# architectures, toolchains, kernel configurations, and make targets.
#
# TuxMake supports the concept of runtimes.
# See https://docs.tuxmake.org/runtimes/, for that to work it requires
# that you install podman or docker on your system.
#
# To install tuxmake on your system globally:
# sudo pip3 install -U tuxmake
#
# See https://docs.tuxmake.org/ for complete documentation.


tuxmake --runtime podman --target-arch arm --toolchain gcc-10
--kconfig s3c6400_defconfig
or
tuxmake --runtime podman --target-arch mips --toolchain gcc-9
--kconfig e55_defconfig

!CONFIG_NET, I guess. Thanks for letting know

Yep, I'm making a cleanup for that.

This should fix it, cleaning it up a bit at the same time.


commit b1c892df32ebf6f30c995e23dcafeae2392ad1bc
Author: Jens Axboe <axboe@kernel.dk>
Date:   Fri Feb 19 09:35:19 2021 -0700

    io_uring: make the !CONFIG_NET helpers a bit more robust
    
    With the prep and prep async split, we now have potentially 3 helpers
    that need to be defined for !CONFIG_NET. Add some helpers to do just
    that.
    
    Fixes the following compile error on !CONFIG_NET:
    
    fs/io_uring.c:6171:10: error: implicit declaration of function
    'io_sendmsg_prep_async'; did you mean 'io_req_prep_async'?
    [-Werror=implicit-function-declaration]
       return io_sendmsg_prep_async(req);
                 ^~~~~~~~~~~~~~~~~~~~~
                 io_req_prep_async
