Also isn't there a second kernel module using this functionality still?
I seem to recall Dell RBU and something else both used it.

Title:
  Please disable long-obsolete CONFIG_FW_LOADER_USER_HELPER

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  The kernel has been able to load firmware by itself for several years
  now, and as a result the userspace loading of firmware got dropped in
  udev three years ago
  (https://github.com/systemd/systemd/commit/be2ea723b1d0).

  But Ubuntu's kernels still enable CONFIG_FW_LOADER_USER_HELPER=y. This
  will cause 60 second delays, unless we explicitly signal the kernel
  back from userspace that we don't use an userspace helper (see
  /lib/udev/rules.d/50-firmware.rules). This is a pointless and resource
  wasting no-op.

  Can we please disable this config option by default? After three years
  there's no sign of the userspace stuff ever coming back. It would also
  be high time to change the default upstream of course.

  Thanks!
