heap-committed-unallocated-fraction is confusing when reading on context of the memory reporters around it since its actually (heap-allocated / heap-committed). It was decided in #memshrink with jlebar that heap-committed-fragmentation was a better name for it.
Created attachment 574516 [details] [diff] [review] Patch Changed reporter path and related variables around with same name.
Pushed to try, at Hugh's request. Results will show up here: https://tbpl.mozilla.org/?tree=Try&rev=4dfae5242574
Created attachment 574535 [details] [diff] [review] PatchV2 V2 now with user and commit message! (hopefully)
Comment on attachment 574535 [details] [diff] [review] PatchV2 Try run looks like it has no fails except unrelated and things that were failing on m-c at push time. So I think the next thing to do is get review, and who better than the person who I needed to ask about the problem in the first place?
Comment on attachment 574535 [details] [diff] [review] PatchV2 lgtm!
