| |
The LSM initialization routines walk security_hook_heads as an array of struct list_head instead of via names to avoid a ton of needless source. Whitelist this to avoid the false positive warning from the plugin:
security/security.c: In function ‘security_init’: security/security.c:59:20: note: found mismatched op0 struct pointer types: ‘struct list_head’ and ‘struct security_hook_heads’
struct list_head *list = (struct list_head *) &security_hook_heads; ^
