[ Upstream commit46a9c526ee] Simplify zonefs_check_zone_condition() by moving the code that changes an inode access rights to the new function zonefs_inode_update_mode(). Furthermore, since on mount an inode wpoffset is always zero when zonefs_check_zone_condition() is called during an inode initialization, the "mount" boolean argument is not necessary for the readonly zone case. This argument is thus removed. zonefs_io_error_cb() is also modified to use the inode offline and zone state flags instead of checking the device zone condition. The multiple calls to zonefs_check_zone_condition() are reduced to the first call on entry, which allows removing the "warn" argument. zonefs_inode_update_mode() is also used to update an inode access rights as zonefs_io_error_cb() modifies the inode flags depending on the volume error handling mode (defined with a mount option). Since an inode mode change differs for read-only zones between mount time and IO error time, the flag ZONEFS_ZONE_INIT_MODE is used to differentiate both cases.

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.
