Subject: [RFC PATCH 0/4] SUNRPC: rework cache upcall to avoid NFSd root swapping
Date: Tue, 15 Jan 2013 11:09:23 +0300 [thread overview]
Message-ID: <20130115080402.2996.74320.stgit@localhost.localdomain> (raw)
The main idea of this patch set is to call cache request not on kthread
upcall, but on userspace daemon cache_read call. This fixes the problem with
gaining of wrong dentry path after calling d_path() in kthread root context
(svc_export_request() callback), which always work in init root context, but
containers can work in "root jail" - i.e. have it's own nested root.
The following series implements...
---
Stanislav Kinsbursky (4):
SUNRPC: introduce cache_detail->cache_request callback
SUNRPC: remove cache_detail->cache_upcall callback
SUNRPC: remove "cache_request" argument in sunrpc_cache_pipe_upcall() function
SUNRPC: move cache_detail->cache_request callback call to cache_read()
