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.

Sounds good to me.  I had a few surprise rejects when merging these
two, which indicates that things might be out of sync.

I presently have:

z3fold-limit-first_num-to-the-actual-range-of-possible-buddy-indexes.patch
z3fold-make-pages_nr-atomic.patch
z3fold-extend-compaction-function.patch
z3fold-use-per-page-spinlock.patch
z3fold-discourage-use-of-pages-that-werent-compacted.patch
z3fold-fix-header-size-related-issues.patch
z3fold-fix-locking-issues.patch
