Subject: [PATCH] percpu: Fix raw_cpu_inc_return()
Date: Thu, 17 Apr 2014 10:43:34 -0700 [thread overview]
Message-ID: <20140417174334.GA20303@linux.vnet.ibm.com> (raw)
This patch fixes a build bug triggered by one of the RCU commits
queued for 3.16.
The definition for raw_cpu_add_return() uses the operation prefix
"raw_add_return_", but the definitions in the various percpu.h files
expect "raw_cpu_add_return_". This commit therefore appropriately
adjusts the definition of raw_cpu_add_return().
