函数名称：ep_rbtree_insert

函数原型：static void ep_rbtree_insert(struct eventpoll *ep, struct epitem *epi)

返回类型：void

参数：

类型参数名称
struct eventpoll *ep
struct epitem *epi
1320  struct rb_node * * p = & rb_node, * parent = NULL
1322  bool leftmost = true
1324  当p循环
1325  parent等于p
1326  epic等于rb_entry(parent, structepitem, rbn)
1327  kcmp等于Compare RB tree keys
1328  如果kcmp大于0则
1329  p等于rb_right
1330  leftmost = false
1331  否则p等于rb_left
1334  rb_link_node( & RB tree node links this structure to the eventpoll RB tree , parent, p)
1335  rb_insert_color_cached( & RB tree node links this structure to the eventpoll RB tree , & RB tree root used to store monitored fd structs , leftmost)
