From: Breno Leitao Date: Tue, 5 Mar 2024 12:15:21 +0000 (-0800) Subject: net: gtp: Leverage core stats allocator X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=660e5aaea11d5ffb6ff2e95f662e38bf1a9c88b9;p=linux.git net: gtp: Leverage core stats allocator With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and convert veth & vrf"), stats allocation could be done on net core instead of in this driver. With this new approach, the driver doesn't have to bother with error handling (allocation failure checking, making sure free happens in the right spot, etc). This is core responsibility now. Remove the allocation in the gtp driver and leverage the network core allocation instead.
