From 2941fcfe04bb2473fdbe07eac48da7ccb74c89ae Mon Sep 17 00:00:00 2001 From: Mikulas Patocka Date: Thu, 5 Dec 2013 17:33:29 -0500 Subject: [PATCH] dm bufio: initialize read-only module parameters commit 4cb57ab4a2e61978f3a9b7d4f53988f30d61c27f upstream. 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.
