Recordmcount uses setjmp/longjmp to manage control flow as it reads and then writes the ELF file. This unusual control flow is hard to follow and check in addition to being unlike kernel coding style. So we rewrite these paths to use regular return values to indicate error/success. When an error or previously-completed object file is found we return an error code following kernel coding conventions -- negative error values and 0 for success when we're not returning a pointer. We return NULL for those that fail and return non-NULL pointers otherwise. One oddity is already_has_rel_mcount -- there we use pointer comparison rather than string comparison to differentiate between previously-processed object files and returning the name of a text section.

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.
