Bjoern A. Zeeb 75ac24a7df LinuxKPI: add cleanup.h for guard DEFINE_GUARD/guard.
iwlwifi v6.11 started to use guard().  _T in the implementation needs
to be exposed to the driver which uses it in DEFINE_GUARD().

Given this is the first instance of attribute(cleanup) in the tree:
- gcc has support for it since at least 2003-06-04
  (0bfa5f65bfb186f10d43304946fd7fcd69988732)
- llvm gained support on 2009-01-31
  (d277d790e0f6f23043397ba919619b5c3e157ff3, llvm-svn 63462).

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
