In swap_entry_put_locked(), we will set slot to SWAP_HAS_CACHE before using swap_entries_free() to do actual swap entry freeing. This introduce an unnecessary intermediate state. By using swap_entries_free() in swap_entry_put_locked(), we can eliminate the need to set slot to SWAP_HAS_CACHE. This change would make the behavior of swap_entry_put_locked() more consistent with other put() operations which will do actual free work after put last reference.

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.
