Subject: [PATCH v1 3/8] libperf cpumap: Hide/reduce scope of MAX_NR_CPUS
Date: Thu,  5 Dec 2024 20:40:30 -0800	[thread overview]
Message-ID: <20241206044035.1062032-4-irogers@google.com> (raw)
In-Reply-To: <20241206044035.1062032-1-irogers@google.com>

Avoid redefinition of MAX_NR_CPUS as a global constant, the original
definition is tools/perf/perf.h.
