Damien Le Moal 2cd2003f7b block: handle zone management operations completions 
[ Upstream commit efae226c2e ]

The functions blk_zone_wplug_handle_reset_or_finish() and
blk_zone_wplug_handle_reset_all() both modify the zone write pointer
offset of zone write plugs that are the target of a reset, reset all or
finish zone management operation. However, these functions do this
modification before the BIO is executed. So if the zone operation fails,
the modified zone write pointer offsets become invalid.

Avoid this by modifying the zone write pointer offset of a zone write
plug that is the target of a zone management operation when the
operation completes. To do so, modify blk_zone_bio_endio() to call the
new function blk_zone_mgmt_bio_endio() which in turn calls the functions
blk_zone_reset_all_bio_endio(), blk_zone_reset_bio_endio() or
blk_zone_finish_bio_endio() depending on the operation of the completed
BIO, to modify a zone write plug write pointer offset accordingly.
These functions are called only if the BIO execution was successful.

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.
