Make them naturally align. pahole output after alignment: struct mlx5_irq { struct atomic_notifier_head nh; /* 0 72 */ /* --- cacheline 1 boundary (64 bytes) was 8 bytes ago --- */ cpumask_var_t mask; /* 72 8 */ char name[32]; /* 80 32 */ struct mlx5_irq_pool * pool; /* 112 8 */ struct kref kref; /* 120 4 */ u32 index; /* 124 4 */ /* --- cacheline 2 boundary (128 bytes) --- */ int irqn; /* 128 4 */ /* size: 136, cachelines: 3, members: 7 */ /* padding: 4 */ /* last cacheline: 8 bytes */ }; Signed-off-by: Shay Drory Reviewed-by: Parav Pandit Signed-off-by: Saeed Mahameed --- drivers/net/ethernet/mellanox/mlx5/core/pci_irq.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers') diff --git a/drivers/net/ethernet/mellanox/mlx5/core/pci_irq.c b/drivers/net/ethernet/mellanox/mlx5/core/pci_irq.c index 9fb75d79bf08..a4f6ba0c91da 100644 --- a/drivers/net/ethernet/mellanox/mlx5/core/pci_irq.c +++ b/drivers/net/ethernet/mellanox/mlx5/core/pci_irq.c @@ -28,13 +28,13 @@ #define MLX5_EQ_REFS_PER_IRQ (2) struct mlx5_irq { - u32 index; struct atomic_notifier_head nh; cpumask_var_t mask; char name[MLX5_MAX_IRQ_NAME]; + struct mlx5_irq_pool *pool; struct kref kref; + u32 index; int irqn; - struct mlx5_irq_pool *pool; }; struct mlx5_irq_pool { -- cgit v1.2.3-58-ga151
