All flags are added to xfs_mount's m_flag instead. Note that the 32bit inode flag was duplicated in both of them, but only cleared in the mount when it was not nessecary due to the filesystem beeing small enough. Two flags are still required here - one to indicate the mount option setting, and one to indicate if it applies or not.
