int ntfs_fill_super (struct super_block * sb, void * opt, const int silent);
ntfs_fill_super is called by the VFS to mount the device described by sb with the mount otions in data with the NTFS filesystem.
If silent is true, remain silent even if errors are detected. This is used during bootup, when the kernel tries to mount the root filesystem with all registered filesystems one after the other until one succeeds. This implies that all filesystems except the correct one will quite correctly and expectedly return an error, but nobody wants to see error messages when in fact this is what is supposed to happen.
sb->s_flags contains the mount options flags.
