[LTP] [PATCH v2 00/11] Introduce guarded buffers

[Cyril Hrubis]

Changes since v1:

* Removed debugging "freeing buffer %p" output and
  added a message that is printed first time tst_alloc() is called.

* Added the missing getpid() to the warning message
  from check_canary()

* Added call to atexit(tst_free_all) in the safe_fork()
  - now we check the canary in child processes as well

* Added documentation into the test-writing-guidelines.txt

* Separated the accept02.c changes from the patch that adds
  the guarded buffers library
