From e3b4a97dbe9741a3227c3ed857a0632532fcd386 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Mon, 7 Dec 2009 13:16:07 -0800 Subject: ocfs2: use allocation reservations for directory data Use the reservations system for unindexed dir tree allocations. We don't bother with the indexed tree as reads from it are mostly random anyway. Directory reservations are marked seperately, to allow the reservations code a chance to optimize their window sizes. This patch allocates only 8 bits for directory windows as they generally are not expected to grow as quickly as file data. Future improvements to dir window sizing can trivially be made.
