   3 Subject: ocfs2/xattr: Only extend xattr bucket in need.
   4 Patch-mainline: 2.6.29
   5
   6 When the first block of a bucket is filled up with xattr
   7 entries, we normally extend the bucket. But if we are
   8 just replace one xattr with small length, we don't need
   9 to extend it. This is important since we will calculate
  10 what we need before the transaction and in this situation
  11 no resources will be allocated.
