From 1b340d0118da1d7c60c664f17d7c8fce2bb1cd9d Mon Sep 17 00:00:00 2001 From: Stanislav Kinsbursky Date: Fri, 25 Nov 2011 17:13:04 +0300 Subject: NFS: DNS resolver cache per network namespace context introduced This patch implements DNS resolver cache creation and registration for each alive network namespace context. This was done by registering NFS per-net operations, responsible for DNS cache allocation/register and unregister/destructioning instead of initialization and destruction of static "nfs_dns_resolve" cache detail (this one was removed). Pointer to network dns resolver cache is stored in new per-net "nfs_net" structure. This patch also changes nfs_dns_resolve_name() function prototype (and it's calls) by adding network pointer parameter, which is used to get proper DNS resolver cache pointer for do_cache_lookup_wait() call. Note: empty nfs_dns_resolver_init() and nfs_dns_resolver_destroy() functions will be used in next patch in the series.
