      wrappers for ->i_mutex access · 5955102c
      Al Viro 提交于
      parallel to mutex_{lock,unlock,trylock,is_locked,lock_nested},
      inode_foo(inode) being mutex_foo(&inode->i_mutex).
      
      Please, use those for access to ->i_mutex; over the coming cycle
      ->i_mutex will become rwsem, with ->lookup() done with it held
      only shared.

      net/mlx5_core: Fix trimming down IRQ number · 0b6e26ce
      Doron Tsur 提交于
      With several ConnectX-4 cards installed on a server, one may receive
      irqn > 255 from the kernel API, which we mistakenly trim to 8bit.
      
      This causes EQ creation failure with the following stack trace:
      [<ffffffff812a11f4>] dump_stack+0x48/0x64
      [<ffffffff810ace21>] __setup_irq+0x3a1/0x4f0
      [<ffffffff810ad7e0>] request_threaded_irq+0x120/0x180
      [<ffffffffa0923660>] ? mlx5_eq_int+0x450/0x450 [mlx5_core]
      [<ffffffffa0922f64>] mlx5_create_map_eq+0x1e4/0x2b0 [mlx5_core]
      [<ffffffffa091de01>] alloc_comp_eqs+0xb1/0x180 [mlx5_core]
      [<ffffffffa091ea99>] mlx5_dev_init+0x5e9/0x6e0 [mlx5_core]
      [<ffffffffa091ec29>] init_one+0x99/0x1c0 [mlx5_core]
      [<ffffffff812e2afc>] local_pci_probe+0x4c/0xa0
      
      Fixing it by changing of the irqn type from u8 to unsigned int to
      support values > 255
      
      Fixes: 61d0e73e ('net/mlx5_core: Use the the real irqn in eq->irqn')
