 Nope. This patch didn't help. r308088 with this patch shows checksum
errors as soon as "ALLOC" on L2ARC becomes greater than "SIZE".

 Also, "zpool list -v" shows "16.0E" of free space:

% zpool list -v
NAME SIZE ALLOC FREE  EXPANDSZ   FRAG    CAP  DEDUP  HEALTH  ALTROOT
...
  gpt/l2arc   185G   189G  16.0E         -     0%   102%
...
