From ca3643171bc6e08b7c4d1f9a2ce659541a01a7fe Mon Sep 17 00:00:00 2001 From: "J.Bruce Fields" Date: Wed, 13 Dec 2006 00:35:27 -0800 Subject: [PATCH] knfsd: nfsd4: pass saved and current fh together into nfsd4 operations Pass the saved and current filehandles together into all the nfsd4 compound operations. I want a unified interface to these operations so we can just call them by pointer and throw out the huge switch statement. Also I'll eventually want a structure like this--that holds the state used during compound processing--for deferral. Signed-off-by: J.
