函数名称：wake_bit_function

函数原型：int wake_bit_function(struct wait_queue_entry *wq_entry, unsigned mode, int sync, void *arg)

返回类型：int

参数：

类型参数名称
struct wait_queue_entry *wq_entry
unsignedmode
intsync
void *arg
23  key等于arg
24  wait_bit等于container_of - cast a member of a structure out to the containing structure*@ptr: the pointer to the member.*@type: the type of the container struct this is embedded in.*@member: the name of the member within the struct.(wq_entry, structwait_bit_queue_entry, wq_entry)
26  如果flags不等于flags或bit_nr不等于bit_nr或st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from则返回:0
31  返回:autoremove_wake_function(wq_entry, mode, sync, key)
