函数名称：iomap_ioend_try_merge

函数原型：void iomap_ioend_try_merge(struct iomap_ioend *ioend, struct list_head *more_ioends, void (*merge_private)(struct iomap_ioend *ioend, struct iomap_ioend *next))

返回类型：void

参数：

类型	参数	名称
struct iomap_ioend *	ioend
struct list_head *	more_ioends
void (*	merge_private

1218

初始化链表头

1220

当next等于list_first_entry_or_null - get the first element from a list*@ptr: the list head to take the element from.*@type: the type of the struct this is embedded in.*@member: the name of the list_head within the struct.(more_ioends, structiomap_ioend, io_list)循环

1222

如果非We can merge two adjacent ioends if they have the same set of work to do.则退出

1224

链表项移动到尾部

1225

size of the extent 加等于size of the extent

1226

如果le system private data 且merge_private则merge_private(ioend, next)
