   4 Subject: ext4: add missing kfree() on error return path in add_new_gdb()
   5 Git-commit: c49bafa3
   6 Patch-mainline: v3.1-rc1

   8 We added some more error handling in b40971426a "ext4: add error
   9 checking to calls to ext4_handle_dirty_metadata()".  But we need to
  10 call kfree() as well to avoid a memory leak.
