Subject: datapath: Add usage of __percpu annotation.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d3097efff7c612e25cbbcf4913c703a73b57e523;p=openvswitch

datapath: Add usage of __percpu annotation.

Sparse can warn if percpu pointers are incorrectly directly
dereference.  This adds the annotation where we declare percpu
pointers.
