From 6ce3b4dcee4f96a5000d3f790403eb6997e3d553 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 24 May 2019 09:03:30 -0700 Subject: inet: rename netns_frags to fqdir 1) struct netns_frags is renamed to struct fqdir This structure is really holding many frag queues in a hash table. 2) (struct inet_frag_queue)->net field is renamed to fqdir since net is generally associated to a 'struct net' pointer in networking stack.
