   1 From: Tiger Yang <tiger.yang@oracle.com>
   2 Date: Fri, 14 Nov 2008 11:16:03 +0800
   3 Subject: ocfs2: add ocfs2_xattr_set_handle
   4 Patch-mainline: 2.6.29
   5
   6 This function is used to set xattr's in a started transaction. It is only
   7 called during inode creation inode for initial security/acl xattrs of the
   8 new inode. These xattrs could be put into ibody or extent block, so xattr
   9 bucket would not be use in this case.
