Johannes Thumshirn 4020d22f0d block: add tracepoint for blkdev_zone_mgmt
Add a tracepoint for blkdev_zone_mgmt to trace zone management commands
submitted by higher layers like file systems or user space.

An example output for this tracepoint is as follows:

  mkfs.btrfs-203  [001] .....  42.877493: blkdev_zone_mgmt: 8,0 ZRS 5242880 + 0

This example output shows a REQ_OP_ZONE_RESET operation submitted by
mkfs.btrfs.

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.
