[PATCH 0/2] lockref tidy ups + touch ups to it's usage by dcache

[Mateusz Guzik]

The open-coded check for < 0 indicating a dead object uses information
it should not know, so to speak.

This is a preliminary clean up for a longer term goal of moving dcache
away from lockref into an approach which can atomic_add both ways
instead of suffering the cmpxchg loop.

Mateusz Guzik (2):
  lockref: tidy up dead count handling
  dcache: use lockref routines for dead count checks
