Really? Commit f18fa5de5ba7 ("net: ieee802154: 6lowpan: fix frag reassembly") says it fixes commit 648700f76b03 ("inet: frags: use rhashtables for reassembly units") which did not show up until 4.17-rc1: $ git describe --contains 648700f76b03 v4.17-rc1~148^2~20^2~11 Also, it did not get backported to 4.16.y, so I don't see how it is needed in 4.16-stable. To verify this, I tried applying the patch, and it totally fails to apply to the 4.16.y tree. So are you _sure_ you want/need this in 4.16? If so, can you provide a working backport that you have verified works? thanks, greg k-h
