When the search key's mantissa is larger than the node i's, we know that the search key is larger than the first key of the cacheline corresponding to node i, so that when we are calculating the mantissa of right side nodes of node i, the left side of the search range can be the first key of node i. Once the search range is minimized, the mantissa we are calculating can have more useful bits, thus reduce the slow path comparison. Besides, we can now remove all the prev array stuff.

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.
