The struct find_free_extent_ctl uses an int for the 'delalloc' field but it's always used as a boolean, and its value is used to be passed to several functions to signal if we are dealing with delalloc. The same goes for the 'is_data' argument from btrfs_reserve_extent(). So change the type from int to bool and move the field definition in the find_free_extent_ctl structure so that it's close to other bool fields and reduces the size of the structure from 144 down to 136 bytes (at the moment it's only declared in the stack of btrfs_reserve_extent(), never allocated otherwise).

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.
