The following three patches remove unecessary locks around ioctls in drm module. First two: [PATCH 1/3] drm: no need to hold global mutex for static data [PATCH 2/3] drm: make DRM_UNLOCKED ioctls with their own mutex are rather trivial and straight forward and probably do not need much explanation. The third one: [PATCH 3/3] drm: do not sleep on vblank while holding a mutex is more serious and clears a clog that can occur if multiple processes call drm_wait_vblank as explained in patch commit message. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
