From ca0e79a46097d54e4af46c67c852479d97af35bb Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 2 Nov 2023 16:08:43 +0000 Subject: afs: Make it possible to find the volumes that are using a server Make it possible to find the afs_volume structs that are using an afs_server struct to aid in breaking volume callbacks. The way this is done is that each afs_volume already has an array of afs_server_entry records that point to the servers where that volume might be found. An afs_volume backpointer and a list node is added to each entry and each entry is then added to an RCU-traversable list on the afs_server to which it points.
