This parameter informs the user about memory consumption. It is not supposed to be changed by the user. However, despite being read-only, this parameter can be set on modprobe or insmod command line: modprobe dm-mod stats_current_allocated_bytes=12345 The kernel doesn't expect that this variable can be non-zero at module initialization and if the user sets it, it results in warning. This patch initializes the variable in the module init routine, so that user-supplied value is ignored.
