[PATCH 2/4] maple_tree: total is not changed for nomem_one case

[Liam R. Howlett]

* Wei Yang <richard.weiyang at gmail.com> [240924 08:41]:
> If it jumps to nomem_one, the total allocated number is not changed. So
> we don't need to adjust it.
> 
> For the nomem_bulk case, we know there is a valid mas->alloc. So we
> don't need to do the check.
