Subject: [PATCH 00/12] maple_tree: slub sheaves conversion

The previous version of this work was part of the patchset that
introduces slub sheaves, but for practical purposes was split out in v6
[1] while Liam did some further fixups and cleanups to the maple tree
and associated testing implementation, incorporating also patches from
Pedro [2] and then provided to me his branch [3] to include it. It
relies on [1] in the slab/for-next tree so the intent is to include this
in slab/for-next as well. More precisely speaking, patches 2 and 3 will
replace the last two patches of [1].
