SELinux: remove redundant exports
Remove the following exported SELinux interfaces: selinux_get_inode_sid(inode, sid) selinux_get_ipc_sid(ipcp, sid) selinux_get_task_sid(tsk, sid) selinux_sid_to_string(sid, ctx, len) They can be substitued with the following generic equivalents respectively: new LSM hook, inode_getsecid(inode, secid) new LSM hook, ipc_getsecid*(ipcp, secid) LSM hook, task_getsecid(tsk, secid) LSM hook, sid_to_secctx(sid, ctx, len) Signed-off-by: Casey Schaufler <casey@schaufler-ca.com> Signed-off-by: Ahmed S.
