Subject: [lttng-dev] [PATCH urcu] fix: bump tests thread limit to 256
Date: Wed, 9 Dec 2020 13:15:37 -0500 [thread overview]
Message-ID: <20201209181537.444048-1-mjeanson@efficios.com> (raw)
Machines with more than 128 CPUs are becomming more common, the proper
fix here would be to dynamically allocate the array which we will do,
but in the meantime bump the limit to 256 to fix the problem on a 160
CPUs ppc64el system where this was reported.
