Subject: mm: memcontrol: drop unused cpu argument from flush_nmi_stats
Date: Mon, 13 Jul 2026 17:00:10 +0800

flush_nmi_stats() does not use its cpu argument.  Remove it from the
function and its !CONFIG_MEMCG_NMI_SAFETY_REQUIRES_ATOMIC stub.  The
caller still uses cpu for the subsequent per-CPU rstat flush.

No functional change.
