From 9df69c81b469780b64f9b26bb87c048613fdeddf Mon Sep 17 00:00:00 2001 From: Stanislav Kinsbursky Date: Fri, 25 Nov 2011 17:13:12 +0300 Subject: NFS: DNS resolver PipeFS notifier introduced This patch subscribes DNS resolver caches to RPC pipefs notifications. Notifier is registering on NFS module load. This notifier callback is responsible for creation/destruction of PipeFS DNS resolver cache directory. Note that no locking required in notifier callback because PipeFS superblock pointer is passed as an argument from it's creation or destruction routine and thus we can be sure about it's validity.
