http://git.kernel.org/?p=linux/kernel/git/mason/btrfs-progs.git I can repeatedly get the following SEGV from running "btrfs device stats" on a device node for an Ext3/4 filesystem. This happens with the version of the code downloaded from the above GIT repository as well as with an older version. Obviously the command in question is not going to do anything useful when run against a non-BTRFS filesystem, but it should do something other than crash.
