From cc37bb04201217b7acb11213e16cb5530c30da8f Mon Sep 17 00:00:00 2001 From: David Sterba Date: Tue, 19 Nov 2013 13:36:21 +0100 Subject: [PATCH] btrfs: replace BUG in can_modify_feature We don't need to crash hard here, it's just reading a sysfs file. The values considered in switch are from a fixed set, the default case should not happen at all.
