Hi SeongJae,
Looks like we missed adding "#include <linux/vmalloc.h>" inside
arch/um/os-Linux/main.c in this patch:
https://lore.kernel.org/all/20240321163705.3067592-2-surenb@google.com/.
I'll be posing fixes for all 0-day issues found over the weekend and
will include a fix for this. In the meantime, to work around it you
can add that include yourself. Please let me know if the issue still
persists after doing that.
Thanks,
Suren.
