Subject: [dpdk-dev] [PATCH 1/2] net/ark: fix leak on thread termination
Date: Thu,  6 May 2021 11:44:51 +0200	[thread overview]
Message-ID: <20210506094452.1689-2-david.marchand@redhat.com> (raw)
In-Reply-To: <20210506094452.1689-1-david.marchand@redhat.com>

A terminated pthread should be joined or detached so that its associated
resources are released.

The "ark-delay-pg" thread is just used to delay some task but it is never
joined by the thread that created it.
The easiest solution is to detach the new thread.

Fixes: 727b3fe292bc ("net/ark: integrate PMD")
Cc: stable@dpdk.org
