Patch series "Reduce the space to be cleared for maple_big_node", v2. Found current code may clear maple_big_node redundantly. First we define a field parent, which is never used. After removing this, we reduce the size of memory to be cleared by memset. Then mast_fill_bnode() clears part of the structure twice, since slot and gap share some space. By clearing the whole structure, we can avoid this. This patch (of 2): The member parent of maple_big_node is never used. Let's remove it which could reduce the number of space to be cleared on memset.

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.
