Why do patches 7 to 13 have a Reply-to: 
20220209170358.3266629-1-atomlin@xxxxxxxxxx and not patches 1 to 6 ?

Having that is module.h  it may redefine some existing symbol, like in 
security/integrity/ima/ima_main.c

sig_enforce is used only in signing.c so it should be defined there 
exclusively. This #define shouldn't be needed at all.



And checkpatch is not happy:

CHECK: Please use a blank line after function/struct/union/enum declarations
#27: FILE: include/linux/module.h:866:
  }
+#define sig_enforce false
