We always use insert_zspage() and remove_zspage() to update zspage's fullness location, which will account correctly. But this special async free path use "splice" instead of remove_zspage(), so the per-fullness zspage count for ZS_INUSE_RATIO_0 won't decrease. Clean things up by decreasing when iterate over the zspage free list. This doesn't actually fix anything. ZS_INUSE_RATIO_0 is just a "placeholder" which is never used anywhere.

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.
