#restorecon -R / ; operation not support

[casinee app <appcasinee@xxxxxxxxx>]

Hi,

when i execute #restorecon -R / , all the output is "... operation not support".  I had check the source code, and in linux/security/selinux/hooks.c :

         ...

sbsec = inode->i_sb->s_security;

if (!(sbsec->flags & SE_SBLABELSUPP))

{

return -EOPNOTSUPP;

}

        ...

it returned. The  SE_SBLABELSUPP defined as 0x40, i want to know how can i do to make the filesystem to support the SecurityContext of selinux. 

Thanks.
