selinux: access superblock_security_struct in LSM blob way
LSM blob has been involved for superblock's security struct. So fix the remaining direct access to sb->s_security by using the LSM blob mechanism. Fixes: 08abe46b2cfc ("selinux: fall back to SECURITY_FS_USE_GENFS if no xattr support") Fixes: 69c4a42d72eb ("lsm,selinux: add new hook to compare new mount to an existing mount") Signed-off-by: GONG, Ruiqi <gongruiqi1@huawei.com> Reviewed-by: Casey Schaufler <casey@schaufler-ca.com> Signed-off-by: Paul Moore <paul@paul-moore.com>
