From 2a50a743bdaab104155bd9e988d2ba3bb4177263 Mon Sep 17 00:00:00 2001 From: Joel Becker Date: Tue, 9 Dec 2008 14:24:33 -0800 Subject: ocfs2: Create ocfs2_xattr_value_buf. When an ocfs2 extended attribute is large enough to require its own allocation tree, we root it with an ocfs2_xattr_value_root. However, these roots can be a part of inodes, xattr blocks, or xattr buckets. Thus, they need a different journal access function for each container. We wrap the bh, its journal access function, and the value root (xv) in a structure called ocfs2_xattr_valu_buf. This is a package that can be passed around. In this first pass, we simply pass it to the extent tree code.
