From 79f8c310dfa52c035e41e46daa25ccf0419bea27 Mon Sep 17 00:00:00 2001 From: Shehjar Tikoo Date: Fri, 7 May 2010 01:53:10 +0000 Subject: rpcsvc: Support multiple vectors during reply submission RPC reply path allows attaching a single iovec to a reply. This limits the replies for certain program ops which need to return multiple vectors for eg, the NFSv3 read reply. Signed-off-by: Shehjar Tikoo Signed-off-by: Anand V.
