The BKL was used into remount_fs pointed function for serialized access to super_block from the others super_operations functions. The function update_sb(), invoked by remount(), seems already well serialized with &root->d_inode->i_mutex. Moreover don't seems there are others super_operations functions in USB core for usbfs that should access to super_block in a way which require BKL.
