You are right. I will update the wording to:
"
mm_vmscan_lru_isolate currently prints only whether the LRU we isolate
from is file or anonymous but we do not know which LRU this is. It is
useful to know whether the list is active or inactive as well as we
use the same function to isolate pages for both of them. Change
the tracepoint to show symbolic names of the lru rather.
"

Does it sound better?

Thanks!
