kernel: perf: Fix event leak upon exec and file release

Linux kernel perf pending task work is never waited upon the matching event release; in the case of a child event, released via freeevent directly, this can potentially result in a leaked event...

kernel: perf: Fix event leak upon exit

A logical flaw exists in the Linux kernel. When a task is scheduled, pending sigtrap deliveries are deferred to the target task upon resuming to userspace via taskwork. However, failures are ignored while adding an event's callback to the taskwork engine. Since the last call for the event exit...
