   3 Subject: ocfs2/xattr: Only set buffer update if it doesn't exist in cache.
   4 Patch-mainline: 2.6.29
   5
   6 When we call ocfs2_init_xattr_bucket, we deem that the new buffer head
   7 will be written to disk immediately, so we just use sb_getblk. But in
   8 some cases the buffer may have already been in ocfs2 uptodate cache,
   9 so we only call ocfs2_set_buffer_uptodate if the buffer head isn't
  10 in the cache.
