Subject: [PATCH] test: Fix race condition in T568-lib-thread.sh
Date: Sun, 14 Feb 2021 20:55:55 -0400 [thread overview]
Message-ID: <20210215005555.4038380-1-david@tethera.net> (raw)
The assignment of thread-ids is (apparently) non-deterministic in a
way that mostly seems to show up on multicore machines. In my tests
the number is different from that previously assumed by this test
about 15% of the time on a 50 thread (25 core) Xeon.
Since message id's are fixed, use a message known to be in the thread
of interest to pick out the correct thread-id.
