Here come 2 patches with z3fold fixes for chunks counting and locking. As
commit 50a50d2 ("z3fold: don't fail kernel build is z3fold_header is too big")
was NAK'ed [1], I would suggest that we removed that one and the next z3fold
commit cc1e9c8 ("z3fold: discourage use of pages that weren't compacted") and
applied the coming 2 instead.Signed-off-by: Vitaly Wool <vitalyw...@gmail.com> [1] https://lkml.org/lkml/2016/11/25/595
