[PATCH] can: fix proc/can/net/rcvlist_* header alignment on 64-bit system

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Before this fix, the function and userdata columns weren't aligned:
  device   can_id   can_mask  function  userdata   matches  ident
   vcan0  92345678  9fffffff  0000000000000000  0000000000000000         0  raw
   vcan0     123    00000123  0000000000000000  0000000000000000         0  raw

After the fix they are:
  device   can_id   can_mask      function          userdata       matches  ident
   vcan0  92345678  9fffffff  0000000000000000  0000000000000000         0  raw
   vcan0     123    00000123  0000000000000000  0000000000000000         0  raw
