Regarding the Subject, are you seeing a double-free error, or it is just an
optimization?
AFAICS, trace_instance_destroy() checks the pointers before calling free().
Why am I asking? because if it is a double-free bug, we need to add the "Fixes:"
tag, otherwise, we can think about a Subject that better describes the patch, like:
"rtla: Do not call trace_instance_destroy() twice on error"
Also, after the "subsystem:," i.e., "rlta:" we need to use capital: e.g.,
"rtla: Fix double free"
Anyways, I see that the code makes sense. I am just trying to improve the
description.
Thanks!
