From 55144768e100b68447f44c5e5c9deb155ad661bd Mon Sep 17 00:00:00 2001 From: Nick Piggin Date: Tue, 16 Oct 2007 01:25:26 -0700 Subject: fs: remove some AOP_TRUNCATED_PAGE prepare/commit_write no longer returns AOP_TRUNCATED_PAGE since OCFS2 and GFS2 were converted to the new aops, so we can make some simplifications for that.
