Hello,
I posted a kernel bug https://bugzilla.kernel.org/show_bug.cgi?id=200651 and
i hope this is the correct place to discuss this.
Could you post the full allocation failure from the kernel log? It's not
possible to vmalloc any additional memory due to the memory pressure, so
this is expected to fail but I'm curious as to the actual allocation that
is triggering it.
