Subject: [PATCH 4.19.y v6 0/2] Double-free bug discovery on testing trigger-field-variable-support.tc

1. About v4-0001-tracing-Remove-hist-trigger-synth_var_refs.patch:

The reason I am backporting this patch is that no one found the double-free bug at that time, then later the code was removed on upstream, but 4.19-stable has the bug.

Both now queued up, thanks
