Now that all framebuffer usage is properly refcounted, we are no longer required to hold the modeset locks while dropping the last reference. Hence implemented a fastpath which avoids the potential stalls associated with grabbing mode_config.lock for the case where there's no other reference around. Explain in a big comment why it is safe. Also update kerneldocs with the new locking rules around drm_framebuffer_remove. Reviewed-by: Rob Clark <rob@ti.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |
