Subject: xfrm: Can "struct netlbl_audit" be killed?

Hello, Casey and Paul.

At the ipsec-next tree,

  /* Audit Information */
  struct xfrm_audit {
  	u32     secid;
  	kuid_t  loginuid;
  	unsigned int sessionid;
  };

has just been killed
( https://git.kernel.org/cgit/linux/kernel/git/klassert/ipsec-next.git/commit/?id=f1370cc4a01e61007ab3020c761cef6b88ae3729 and
  https://git.kernel.org/cgit/linux/kernel/git/klassert/ipsec-next.git/commit/?id=2e71029e2c32ecd59a2e8f351517bfbbad42ac11 )
because these arguments are always calculated from current thread's security
context.

Looking at other security_secid_to_secctx() users, I noticed that
a similar struct in the netlabel code.

  /* NetLabel audit information */
  struct netlbl_audit {
  	u32 secid;
  	kuid_t loginuid;
  	unsigned int sessionid;
  };

Do you know whether we can kill "struct netlbl_audit" as well?
(In other words, is "bool" sufficient for representing "struct netlbl_audit" ?)

Regards.
