This was a trick implemented to handle the case where we had a giant reservation in front of a bunch of little reservations in the ticket queue. If the giant reservation was too large for the transaction commit to make a difference we'd ENOSPC everybody out instead of committing the transaction. This logic was put in to force us to go back and re-try the transaction commit logic to see if we could make progress. Instead now we know we've committed the transaction, so any space that would have been recovered is now available, and would be caught by the btrfs_try_granting_tickets() in this loop, so we no longer need this code and can simply delete it.

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.
