mainlining shenanigans
35e882a444
If the caller supplies more than 4G of objects and than one that has to be in the low 4G, it is possible for the low 4G to be full before we attempt to find room for the last object that must be there. As we don't reorder the two types, every pass hits the same problem and we fail with ENOSPC. However, if we impose a little bit of ordering between the two classes of objects, on the second pass we will be able to fit the special object as we do it first. For setups that only use !48b objects, we now reverse the order between passes, hopefully making the subsequent passes more likely to succeed given that we are trying a different order (rather than repeating the previous pass!) v2: Quick one line explanation for the relative priorities given to reservations.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
