Now that btrfs_space_info_add_old_bytes simply checks if we can make the reservation and updates bytes_may_use, there's no reason to have both helpers in place. Factor out the ticket wakeup logic into it's own helper, make btrfs_space_info_add_old_bytes() update bytes_may_use and then call the wakeup helper, and replace all calls to btrfs_space_info_add_new_bytes() with the wakeup helper.

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.
