Re: [PATCH v20 08/23] LSM: Use lsmblob in security_ipc_getsecid

There may be more than one LSM that provides IPC data for auditing. Change security_ipc_getsecid() to fill in a lsmblob structure instead of the u32 secid. The audit data structure containing the secid will be updated later, so there is a bit of scaffolding here.
