From b446b60e4eb5e5457120c4728ada871b1209c1d0 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Tue, 20 Feb 2007 13:57:48 -0800 Subject: [PATCH] rework reserved major handling Several people have reported failures in dynamic major device number handling due to the recent changes in there to avoid handing out the local/experimental majors. Rolf reports that this is due to a gcc-4.1.0 bug. The patch refactors that code a lot in an attempt to provoke the compiler into behaving.
