      hlist: drop the node parameter from iterators · b67bfe0d
      Sasha Levin 提交于
      I'm not sure why, but the hlist for each entry iterators were conceived
      
              list_for_each_entry(pos, head, member)
      
      The hlist ones were greedy and wanted an extra parameter:
      
              hlist_for_each_entry(tpos, pos, head, member)
      
      Why did they need an extra pos parameter? I'm not quite sure. Not only
      they don't really need it, it also prevents the iterator from looking
      exactly like the list iterator, which is unfortunate.
      
      Besides the semantic patch, there was some manual work required:
      
       - Fix up the actual hlist iterators in linux/list.h
       - Fix up the declaration of other iterators based on the hlist ones.
       - A very small amount of places were using the 'node' parameter, this
       was modified to use 'obj->member' instead.
       - Coccinelle didn't handle the hlist_for_each_entry_safe iterator
       properly, so those had to be fixed up manually.
      
      The semantic patch which is mostly the work of Peter Senna Tschudin is here:

      batman-adv: fix random jitter calculation · 143cdd8f
      Akinobu Mita 提交于
      batadv_iv_ogm_emit_send_time() attempts to calculates a random integer
      in the range of 'orig_interval +- BATADV_JITTER' by the below lines.
      
              msecs = atomic_read(&bat_priv->orig_interval) - BATADV_JITTER;
              msecs += (random32() % 2 * BATADV_JITTER);
      
      But it actually gets 'orig_interval' or 'orig_interval - BATADV_JITTER'
      because '%' and '*' have same precedence and associativity is
      left-to-right.
      
      This adds the parentheses at the appropriate position so that it matches
      original intension.
