From 3a0782d09c07aa3ec767ba6089cd15cfbfbfc508 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Wed, 17 Jan 2007 12:53:31 -0800 Subject: [PATCH] ocfs2: teach extend/truncate about sparse files For ocfs2_truncate_file(), we eliminate the "simple" truncate case which no longer exists since i_size is not tied to i_clusters. In ocfs2_extend_file(), we skip the allocation / page zeroing code for file systems which understand sparse files. The core truncate code is changed to do a bottom up tree traversal. This gets abstracted out into it's own function. To make things more readable, most of the special case handling for in-inode extents from ocfs2_do_truncate() is also removed. Though write support for sparse files comes in a later patch, we at least update ocfs2_prepare_inode_for_write() to skip allocation for sparse files.
