Patch 1/2: some fields of the maple_alloc is not necessary to change, so we
           can skip some operations
Patch 3: a valid alloc check could be hide in current code, so we don't need
         to do a separate check
Patch 4: found on rare case where allocation would fail even has enough
         memory

Wei Yang (4):
  maple_tree: clear request_count for new allocated one
  maple_tree: total is not changed for nomem_one case
  maple_tree: simplify mas_push_node()
  maple_tree: fix potential allocation failure even has memory

Andrew - Liam is away at the moment - could we hold off on taking this
series to unstable until he's back and had a chance to review please?

It may be best to avoid taking maple tree changes other than urgent bug
fixes or the like until his return also.

Wei - please hold off on series like this until Liam's had a chance to
reply to this thread. Thanks!

Sure, let me know when it is ok.

BTW, I don't see Andrew has taken it in unstable. Do I miss the mail?

Thanks, Liam should reply to the thread once he's back then we're good to
go :)

Yeah he's not taken yet, kind of getting ahead of things here - not a
comment on your series - more an act of time/resource management :)

Cheers!
