Hi zhouxianrong,
Please could you be more sepcific what case can we encounter below BUG?
(Please use plain text)
What zs_class size did you this this problem?
Could you say how that can happen?
As I wrote in other reply, zsmalloc should never allocate last parital
object when I look at source

The last partial object in last subpage of zspage should not be linked
in allocation list. Otherwise it could trigger BUG_ON explicitly at
function zs_map_object. But it happened rarely.

Please expand the changelog. Why it should not be? What happens if it
is? Kernel panic, data corruption or whatnot? So that people not
familiar with zsmalloc
