Damien Le Moal 19de03b312 block: make REQ_OP_ZONE_OPEN a write operation
A REQ_OP_OPEN_ZONE request changes the condition of a sequential zone of
a zoned block device to the explicitly open condition
(BLK_ZONE_COND_EXP_OPEN). As such, it should be considered a write
operation.

Change this operation code to be an odd number to reflect this. The
following operation numbers are changed to keep the numbering compact.

No problems were reported without this change as this operation has no
data. However, this unifies the zone operation to reflect that they
modify the device state and also allows strengthening checks in the
block layer, e.g. checking if this operation is not issued against a
read-only device.

Fixes: 6c1b1da58f ("block: add zone open, close and finish operations")

README

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 reStructuredText 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.
