From 9f255651fb41c111ee35a2ae632df8ce9bd61def Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Tue, 6 May 2008 22:24:04 +0200 Subject: [PATCH] kobject: replace '/' with '!' in name Some (block) devices have a '/' in the name, and need special handling. Let's have that rule to the core, so we can remove it from the block class.
