Subject: [PATCH 2/7] libnuma: do not recalculate maxconfiguredcpu
Date: Thu, 16 Aug 2012 17:16:31 +0200 [thread overview]
Message-ID: <1345130196-24180-3-git-send-email-pholasek@redhat.com> (raw)
In-Reply-To: <1345130196-24180-1-git-send-email-pholasek@redhat.com>
The value for maxtconfiguredcpu is already calculated before
set_thread_constraints() is called, so there is no reason to
call sysconf(_SC_NPROCESSORS_CONF) a second time. Instead just
use the global maxconfiguredcpu.
