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.

Which filesystem is this?
