From 97aff52ae13d3c11a074bbbfc80ad0b59cb8cdeb Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Wed, 19 Nov 2008 16:48:41 +0800 Subject: [PATCH] ocfs2/xattr: Fix a bug in xattr allocation estimation When we extend one xattr's value to a large size, the old value size might be smaller than the size of a value root. In those cases, we still need to guess the metadata allocation.
