+13. file.o: warning: func()+0x2a: non __ro_after_init static key "key" in .noinstr section
+
+  This means that the noinstr function func() uses a static key that can be
+  modified at runtime. This is not allowed as noinstr functions rely on
+  containing stable instructions after init.
+
+  Check whether the static key in question can really be modified at runtime,
+  and if it is only enabled during init then mark it as __ro_after_init. If it
+  genuinely needs to be modified at runtime:
+
+  1) Directly rely on the underlying atomic count of they key in the noinstr
+     functions.
+  2) Mark the static key as forceful.
 
 If the error doesn't seem to make sense, it could be a bug in objtool.
 Feel free to ask the objtool maintainer for help.
