btrfs: compression: allocate heuristic buckets with workspace

Browse source

Avoid allocating the heuristic buckets separately from the workspace,
the lifetime is the same.

The new size of struct heuristic_ws is 2112.  SLUB merges same/similar
sized structures for the named caches, so there's a chance such size
already exists on the system, like below:

  $ grep 2112 /proc/slabinfo
  sighand_cache        593   1335   2112   15   8
