>> WARNING: modpost: vmlinux.o(.text+0x48087): Section mismatch in reference from the function resctrl_init() to the function .init.text:thread_throttle_mode_init()
The function resctrl_init() references
the function __init thread_throttle_mode_init().
This is often because resctrl_init lacks a __init
annotation or the annotation of thread_throttle_mode_init is wrong.
