Subject: Fix: sessiond: silent kernel notifier registration error
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=7ebbf3f02689e6d437206297230cbf264f67e3be;p=lttng-tools.git

Fix: sessiond: silent kernel notifier registration error

When a kernel notifier fails to be registered, the error is silently
ignored because of a missing jump to the error label.

This was noticed while debugging an unrelated problem where the kernel
tracer would fail to add a userspace probe to a semaphore-protected SDT
probe.
