To allow applications to easily check the current usage status of the open zone resources of the mounted device, export through sysfs the counter of write open sequential files s_wro_seq_files field of struct zonefs_sb_info. The attribute is named nr_wro_seq_files and is read only. The maximum number of write open sequential files (zones) indicated by the s_max_wro_seq_files field of struct zonefs_sb_info is also exported as the read only attribute max_wro_seq_files.
