From 50db5aefa18283282400fd4a5090b686b5870206 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Fri, 25 Jul 2008 13:30:08 +1000 Subject: drm: don't set the signal blocker on the master process. this lets us debug the X server through xkb startup. Not sure what the correct answer is, probably X needs to drop the lock when execing stuff, with input hotplug it can get xkb stuff at any time I believe. --- linux-core/drm_lock.c | 21 +++++++++++++-------- 1 file changed, 13 insertions(+), 8 deletions(-) diff --git a/linux-core/drm_lock.c b/linux-core/drm_lock.c index d4c2da0c..573213de 100644 --- a/linux-core/drm_lock.c +++ b/linux-core/drm_lock.c @@ -105,14 +105,19 @@ int drm_lock(struct drm_device *dev, void *data, struct drm_file *file_priv) ret ?
