Message-ID: <20130115080936.2996.1659.stgit@localhost.localdomain>
Date: Tue, 15 Jan 2013 11:09:36 +0300
From: Stanislav Kinsbursky <skinsbursky@...allels.com>

Subject: [PATCH 2/4] SUNRPC: remove cache_detail->cache_upcall callback
This callback is redundant since all that its' implementations are doing is
calling sunrpc_cache_pipe_upcall() with proper function address argument. This
function address is now stored on cache_detail structure and thus all the code
can be simplified.
