Subject: [PATCH 24/48] rcu: Replace __this_cpu_ptr uses with raw_cpu_ptr
Date: Fri, 14 Feb 2014 14:19:05 -0600 [thread overview]
Message-ID: <20140214201906.486328867@linux.com> (raw)
In-Reply-To: 20140214201841.826179349@linux.com
[-- Attachment #1: this_rcu --]
[-- Type: text/plain, Size: 2163 bytes --]
[Patch depends on another patch in this series that introduces raw_cpu_ops]
__this_cpu_ptr is being phased out.
One special case is increment_cpu_stall_ticks().
A per cpu variable is incremented so use raw_cpu_inc().
