From 6707bd3d420f53ae8f090dac871843f6f43c9980 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Fri, 1 May 2009 19:57:46 -0400 Subject: nfsd4: remove unused dl_trunc There's no point in keeping this field around--it's always zero. (Background: the protocol allows you to tell the client that the file is about to be truncated, as an optimization to save the client from writing back dirty pages that will just be discarded. We don't implement this hint. If we do some day, adding this field back in will be the least of the work involved.) Signed-off-by: J.
