I am not sure how people are using partial object accounting. I
believe it is used as a memory usage hint of slabs.

Uh, that's interesting. Would you know what exactly it uses the value for? I can
think of several reasons why it might be
More precisely, ss will count partial objects like denty objects with
"/sys/kernel/slab/dentry/partial" whose number can become huge.

The node list_lock in count_partial() spends long time iterating
in case of large amount of partial page lists, which can cause
thunder herd effect to the list_lock contention.
We have HSF RT(High-speed Service Framework Response-Time) monitors,
the RT figures fluctuated randomly, then we
