Unconditionally? User controlable?
Unconditionally, it's a single line of output per slab cache and there
can't be that many of them if each is using >5% of memory.
So，you mean just dump the single slab cache if its size > 5% of system memory
instead of all slab caches?
Yes, this should catch occurrences of "huge unreclaimable slabs", right?
Yes, it sounds so. Although single "huge" unreclaimable slab might not
result in excessive slabs use in a whole, but this would help to filter
out "small" unreclaimable slab.
