      net: eql: Use kzalloc instead of kmalloc/memset · 9c8774e6
      Haowen Bai authored
      Use kzalloc rather than duplicating its implementation, which
      makes code simple and easy to understand.

      drivers: net: hippi: Fix deadlock in rr_close() · bc6de287
      Duoming Zhou authored
      There is a deadlock in rr_close(), which is shown below:
      
         (Thread 1)                |      (Thread 2)
                                   | rr_open()
      rr_close()                   |  add_timer()
       spin_lock_irqsave() //(1)   |  (wait a time)
       ...                         | rr_timer()
       del_timer_sync()            |  spin_lock_irqsave() //(2)
       (wait timer to stop)        |  ...
      
      We hold rrpriv->lock in position (1) of thread 1 and
      use del_timer_sync() to wait timer to stop, but timer handler
      also need rrpriv->lock in position (2) of thread 2.
      As a result, rr_close() will block forever.
      
      This patch extracts del_timer_sync() from the protection of
      spin_lock_irqsave(), which could let timer handler to obtain
      the needed lock.
