 "This consists of a cleanup patch to undo changes to global .gitignore
  that added selftests/lkdtm objects and add them to a local
  selftests/lkdtm/.gitignore.

  Summary of Linus's comments on local vs. global gitignore scope:

   - Keep local gitignore patterns in local files.

   - Put only global gitignore patterns in the top-level gitignore file.

  Local scope keeps things much better separated. It also incidentally
  means that if a directory gets renamed, the gitignore file continues
  to work unless in the case of renaming the actual files themselves
  that are named in the gitignore"

Commit 68ca0fd272da ("selftest/lkdtm: Don't pollute 'git status'")
introduced patterns for git to ignore files generated in
tools/testing/selftests/lkdtm/

Use local .gitignore file instead of using the root one.

Add a specific test for the crash reported by Phil Sutter and addressed
in the previous patch. The test cases that, in my intention, should
have covered these cases, that is, the ones from the 'concurrency'
section, don't run these sequences tightly enough and spectacularly
failed to catch this.

While at it, define a convenient way to add these kind of tests, by
adding a "reported issues" test section.

It's more convenient, for this particular test, to execute the set
setup in its own function. However, future test cases like this one
might need to call setup functions, and will typically need no tools
other than nft, so allow for this in check_tools().

The original form of the reproducer used here was provided by Phil.
