> Note the duplicate "kernel/" in the path for test_udelay.ko and configs.ko.
The paths to test_udelay.ko and configs.ko look quite normal to me.
"kernel/kernel/" is correct.
The first "kernel/" means in-tree modules.
All in-tree modules are installed
under /lib/modules/<ver>/kernel/,
while external modules are installed
under /lib/modules/<ver>/updates/.
The second "kernel/" is the directory in the source tree.
I cannot reproduce the error.
But, indeed. Your installation log looks weird overall.
No idea what is happening in your case.
If you add V=1, Kbuild will show more logs, and we may get more hints.
make V=1 -j72 modules_install INSTALL_MOD_PATH=${TMPDIR}
BTW, you are not testing linux-next, right?

Add linux-next specific files for 20230831
Signed-off-by: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Apparently, your version
"6.5.0-next-20230831-13697-g09d3bd189478-dirty" is different.
I cannot find commit 09d3bd189478.
And, it seems a lot of local patches applied on top.
Next time, please send repro steps for linux-next.
