Some module parameters in dm-bufio are read-only. These parameters inform the user about memory consumption. They are not supposed to be changed by the user. However, despite being read-only, these parameters can be set on modprobe or insmod command line, for example: modprobe dm-bufio current_allocated_bytes=12345 The kernel doesn't expect that these variables can be non-zero at module initialization and if the user sets them, it results in BUG. This patch initializes the variables in the module init routine, so that user-supplied values are ignored.
