Subject: mm/damon/dbgfs: remove an unnecessary variable
Patch series "mm/damon: Hide unnecessary information disclosures".
DAMON is exposing some unnecessary information including kernel pointer
in kernel log and tracepoint. This patchset hides such information.
The first patch is only for a trivial cleanup, though.
This patch (of 4):
This commit removes a unnecessarily used variable in
dbgfs_target_ids_write().
