Subject: [PATCH v5 5/5] selftests/ftrace: Update synthetic event syntax errors
Date:   Mon, 21 Dec 2020 15:44:31 -0600
Message-Id: <d314da19a66934f82102cffee104daaf72c32773.1608586464.git.zanussi@kernel.org>

Precedence: bulk

Some of the synthetic event errors and positions have changed in the
code - update those and add several more tests.

Also add a runtime check to ensure that the kernel supports dynamic
strings in synthetic events, which these tests require.

Fixes: 81ff92a93d95 (selftests/ftrace: Add test case for synthetic
event syntax errors)
