From 33d5d380d667ad264675cfdb297dfc3c5b6542cc Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Wed, 24 Feb 2010 13:34:09 -0800 Subject: [PATCH] ocfs2: allocate btree internal block groups from the global bitmap Otherwise, the need for a very large contiguous allocation tends to wreak havoc on many inode allocation reservations on the local alloc, thus ruining any chances for contiguousness.
