From 15c6fd9786dfaab43547bf60df6fa63170fb64fc Mon Sep 17 00:00:00 2001 From: "npiggin@suse.de" Date: Thu, 27 May 2010 01:05:34 +1000 Subject: kill spurious reference to vmtruncate Lots of filesystems calls vmtruncate despite not implementing the old ->truncate method. Switch them to use simple_setsize and add some comments about the truncate code where it seems fitting.
