Input: uinput - add devname alias to allow module on-demand load (8905aaaf) · Commits · 戴 / test

Recent modprobe and udev versions allow to create device nodes for modules which are not loaded. Only the first access will cause the in-kernel module loader to pull-in the module. Systems which never access the device node will not needlessly load the module, and no longer need init scripts or other facilities to unconditionally load it. Signed-off-by:
