From 2ae99a60374f360ba07037ebbf33d19b89ac43a6 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Fri, 9 Mar 2007 16:43:28 -0800 Subject: ocfs2: Support creation of unwritten extents This can now be trivially supported with re-use of our existing extend code. ocfs2_allocate_unwritten_extents() takes a start offset and a byte length and iterates over the inode, adding extents (marked as unwritten) until len is reached. Existing extents are skipped over.
