[Xen-devel] [PATCH v4 2/3] net/xen-netback: Remove unused code in xenvif_rx_action

[Julien Grall <julien.grall@xxxxxxxxxx>]

The variables old_req_cons and ring_slots_used are assigned but never
used since commit 1650d5455bd2dc6b5ee134bd6fc1a3236c266b5b "xen-netback:
always fully coalesce guest Rx packets".
