This patch creates a helper function for handling zoned block device operations. This patch also restructured the code for null_blk_zoned.c and uses the pattern to return blk_status_t and catch the error in the function null_handle_cmd() into cmd->error variable instead of setting it up in the deeper layer just like the way it is done for flush, badblocks and memory backed case in the null_handle_cmd(). We also move null_handle_zoned() to the null_blk_zoned.c to keep the zoned code separate. Signed-off-by: Chaitanya Kulkarni <chaitanya.kulkarni@wdc.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
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.
