I get a build failure on v6.10-rc5 on my Talos II when MEM_ALLOC_PROFILING=y is enabled:

Same .config builds fine without MEM_ALLOC_PROFILING set. Kernel .config attached.
Build problem still there on now released v6.10 with MEM_ALLOC_PROFILING=y.
Can't bisect as build with MEM_ALLOC_PROFILING fails since it's introduction in v6.10-rc1.
I guess those three functions are missing EXPORT_SYMBOL_GPL() tagging.
The issue should have been fixed by
https://lore.kernel.org/all/20240717181239.2510054-1-surenb@google.com/ (local)
patchset. I probably forgot to CC stable@ for these changes. Let me
check and follow up.
Thanks,
Suren.
