From 0129241e2b3b90ff83a8c774353e5612d84bd493 Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Mon, 21 Sep 2009 13:04:19 +0800 Subject: ocfs2: Attach xattr clusters to refcount tree. In ocfs2, when xattr's value is larger than OCFS2_XATTR_INLINE_SIZE, it will be kept outside of the blocks we store xattr entry. And they are stored in a b-tree also. So this patch try to attach all these clusters to refcount tree also.

Now with xattr refcount support, we need to check whether we have xattr refcounted before we remove the refcount tree. Now the mechanism is: 1) Check whether i_clusters == 0, if no, exit. 2) check whether we have i_xattr_loc in dinode. if yes, exit. 2) Check whether we have inline xattr stored outside, if yes, exit. 4) Remove the tree.
