From 2d6e4ecc87d20299bcb249dd62efbd73496744c3 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Wed, 16 Sep 2009 12:11:54 -0700 Subject: md/raid6: eliminate BUG_ON with side effect As pointed out by Neil it should be possible to build a driver with all BUG_ON statements deleted. It's bad form to have a BUG_ON with a side effect.
