[QUESTION] mm: Redundant const parameter?

[Dev Jain]

Hi Chengming,

In mm/slub.c, you had defined slab_test_node_partial() to take a const 
parameter.

Is there any point of taking in a const, when you are anyways 
typecasting it to

a (struct folio *) from (const struct folio *) ? In fact, at the place 
where you call

slab_test_node_partial(), the struct slab *slab is not const.

Please comment.


Thanks
