During an incremental send, before determining if we need to send a hole (write operations full of zeroes) we will search for the last extent's end offset if we are at the first slot of a leaf and the last processed extent's end offset is smaller then the current extent's start offset. However we are repeating this search in case we had the last extent's end offset undefined (set to the (u64)-1 value) when we entered maybe_send_hole(), wasting time. So avoid this duplicated search by combining the two conditions that trigger a search for the last extent's end offset into a single if statement.

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.
