Re: [PATCH v26 17/25] LSM: Use lsmcontext in security_inode_getsecctx

Change the security_inode_getsecctx() interface to fill a lsmcontext structure instead of data and length pointers. This provides the information about which LSM created the context so that security_release_secctx() can use the correct hook.
