cluster/afr: Set lk-owner to pid when fuse does not supply it.v3.0.5rc7
Use the frame->root address as lk-owner when FUSE does not supply lk_owner. Raghu, I unit tested this patch with dbench and self heal tests. Did not observe lk-owner=0 in any server logs. Can you verify this patch with the other tests you had run today? Signed-off-by: Pavan Vilas Sondur <pavan@gluster.com> Signed-off-by: Anand V.
