Miaohe Lin ce8475b6a4 mm/zsmalloc.c: remove confusing code in obj_free()
Patch series "Cleanup for zsmalloc".

This series contains cleanups to remove confusing code in obj_free(),
combine two atomic ops and improve readability for async_free_zspage().
More details can be found in the respective changelogs.

This patch (of 2):

OBJ_ALLOCATED_TAG is only set for handle to indicate allocated object.
It's irrelevant with obj.  So remove this misleading code to improve
readability.

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.
