From 80df9d202255071c8ec610a6a3fdca5cac69f7bd Mon Sep 17 00:00:00 2001 From: Stanislav Kinsbursky Date: Wed, 11 Jan 2012 19:18:17 +0400 Subject: SUNRPC: subscribe RPC clients to pipefs notifications This patch subscribes RPC clients to RPC pipefs notifications. RPC clients notifier block is registering with pipefs initialization during SUNRPC module init. This notifier callback is responsible for RPC client PipeFS directory and GSS pipes creation. For pipes creation and destruction two additional callbacks were added to struct rpc_authops. 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.
