Subject: What is the difference between percpu_xxx and this_cpu_xxx?
Date: Tue, 13 Sep 2011 12:28:43 +0800 [thread overview]
Message-ID: <4E6EDBFB.4010705@intel.com> (raw)
Hi,
If my understanding was correct, from the kernel source code, it appears
that percpu_xxx and this_cpu_xxx have the same semantics and
implementation in effect, haven’t them?
If so, why do we need two API for the same thing?
Best Regards,
Huang Ying
