Description:
fil_n_file_opened is used to display the number of open files for InnoDB monitor and  status variable.

Real accounting of the number of open files is done by Fil_shard::s_n_open atomic variable

fil_n_file_opened is updated each time we increment or decrement s_n_open

It would be better to provide a function to access the current value of s_n_open instead.
