Because enable_swap_slots_cache can only become true in enable_swap_slots_cache(), and depends on swap_slot_cache_initialized is true before. That means, when enable_swap_slots_cache is true, swap_slot_cache_initialized is true also. So the condition: "swap_slot_cache_enabled && swap_slot_cache_initialized" can be reduced to "swap_slot_cache_enabled" And in mathematics: "!swap_slot_cache_enabled || !swap_slot_cache_initialized" is equal to "!(swap_slot_cache_enabled && swap_slot_cache_initialized)" So no functional change.

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.
