Here are some improvements to the lru_cache; mostly just cleanups that
we missed to send upstream over the years.

The last patch makes the SPDX license headers in DRBD consistent so
that they all represent GPL 2.0.

Christoph Böhmwalder (2):
  lru_cache: remove compiled out code
  drbd: use consistent license

Joel Colledge (1):
  lru_cache: remove unused lc_private, lc_set, lc_index_of

Lars Ellenberg (1):
  lru_cache: use atomic operations when accessing lc->flags, always
