Usually the autodefer helpers in lib.sh are expected to be run in context where success is the expected outcome. However when using them for feature detection, failure can legitimately occur. But the failed command still schedules a cleanup, which will likely fail again. Instead, only schedule deferred cleanup when the positive command succeeds. This way of organizing the cleanup has the added benefit that now the return code from these functions reflects whether the command passed.

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 reStructuredText 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.
