Currently the error case for the priority tickets is handled where we deal with all of the tickets, priority and non-priority. This is OK in general, but it makes for some awkward locking. We take and drop the space_info->lock back to back because of these different types of tickets. Rework the code to handle priority ticket failures in their respective helpers. This allows us to be less wonky with our space_info->lock usage, and means that the main handler simply has to check ticket->error, as the ticket is guaranteed to be off any list and completely handled by the time it exits one of the handlers.

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.
