From 7aeeaedc5f73fa304849b8768de455ab5dae49a4 Mon Sep 17 00:00:00 2001 From: Alan Jenkins Date: Thu, 23 Oct 2008 19:37:30 +0100 Subject: [PATCH] udevd: fix WAIT_FOR_SYSFS execution order The wait should be ordered after matching KERNEL, ENV, etc. but before ATTR. Without this, WAIT_FOR_SYSFS rules will be applied unconditionally to all events.
