Patch series "add common struct mm_slot and use it in THP and KSM", v2. At present, both THP and KSM module have similar structures mm_slot for organizing and recording the information required for scanning mm, and each defines the following exactly the same operation functions: - alloc_mm_slot - free_mm_slot - get_mm_slot - insert_to_mm_slots_hash In order to de-duplicate these codes, this patchset introduces a common struct mm_slot, and lets THP and KSM to use it. This patch (of 7): At present, both THP and KSM module have similar structures mm_slot for organizing and recording the information required for scanning mm, and each defines the following exactly the same operation functions: - alloc_mm_slot - free_mm_slot - get_mm_slot - insert_to_mm_slots_hash In order to de-duplicate these codes, this patch introduces a common struct mm_slot, and subsequent patches will let THP and KSM to use it.

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.
