Commit Message

Paolo Abeni Jan. 18, 2022, 3:24 p.m. UTC 
After commit 5e10da5385d2 ("skbuff: allow 'slow_gro' for skb
carring sock reference") and commit af352460b465 ("net: fix GRO
skb truesize update") the truesize of freed skb is properly updated
by the GRO engine, we don't need anymore resetting it at recycle time.
