The linux-next integration testing tree
043b3f7b63
Rather than a fixed-size array of pending sorted runs, use the ->prev links to keep track of things. This reduces stack usage, eliminates some ugly overflow handling, and reduces the code size. Also: * merge() no longer needs to handle NULL inputs, so simplify. * The same applies to merge_and_restore_back_links(), which is renamed to the less ponderous merge_final(). (It's a static helper function, so we don't need a super-descriptive name; comments will do.) * Document the actual return value requirements on the (*cmp)() function; some callers are already using this feature. x86-64 code size 1086 -> 739 bytes (-347) (Yes, I see checkpatch complaining about no space after comma in "__attribute__((nonnull(2,3,4,5)))". Checkpatch is wrong.) Feedback from Rasmus Villemoes, Andy Shevchenko and Geert Uytterhoeven.

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.
