Subject: [PATCH net-next] net/mlx5: Remove redundant memset after kvzalloc
Date: Tue, 13 Oct 2026 00:03:10 +0900 [thread overview]
Message-ID: <20261012150311.555104-1-ekffu200098@gmail.com> (raw)
kvzalloc() returns zeroed memory, so the memset after the allocation in
mlx5e_post_meter_create_mtu_table() and macsec_fs_tx_create() is
redundant.
So remove the memset.
No functional change.
