Subject: [dpdk-stable] [PATCH 1/3] eal/windows: fix use of incorrect thread ID
Date: Sun,  2 May 2021 05:33:31 +0300
Message-ID: <20210502023333.30351-1-dmitry.kozliuk@gmail.com> (raw)

Interrupt thread ID retained its value after interrupt thread finish.
Other interrupt routines could then operate on the wrong thread.
Clear interrupt thread ID before thread termination.

Fixes: 5c016fc0205a ("eal/windows: add interrupt thread skeleton")
Cc: stable@dpdk.org
