From c08d3b0e33edce28e9cfa7b64f7fe5bdeeb29248 Mon Sep 17 00:00:00 2001 From: npiggin@suse.de Date: Fri, 21 Aug 2009 02:35:06 +1000 Subject: truncate: use new helpers Update some fs code to make use of new helper functions introduced in the previous patch. Should be no significant change in behaviour (except CIFS now calls send_sig under i_lock, via inode_newsize_ok).
