The explicit_open mount option forces an explicitly open of the zone of sequential files that are open for writing to ensure that the open file can be written without the device failing write operations due to open zone resources limit being exceeded. To implement this, zonefs accounts all write open seq file when this mount option is used. This accounting however can be easily performed even when the explicit_open mount option is not used, thus allowing applications to control zone resources on their own, without relying on open() system call failures from zonefs. To implement this, the helper zonefs_file_use_exp_open() is removed and replaced with the helper zonefs_seq_file_need_wro() which test if a file is a sequential file being open with write access. zonefs_open_zone() and zonefs_close_zone() are renamed respectively to zonefs_seq_file_write_open() and zonefs_seq_file_write_close() and modified to update the s_wro_seq_files counter regardless of the explicit_open mount option use. If the explicit_open mount option is used, zonefs_seq_file_write_open() execute an explicit zone open operation for a sequential file open for writing for the first time, as before.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
