block_write

函数名称：block_write_end

函数原型：int block_write_end(struct file *file, struct address_space *mapping, loff_t pos, unsigned len, unsigned copied, struct page *page, void *fsdata)

返回类型：int

参数：

类型	参数	名称
struct file *	file
struct address_space *	mapping
loff_t	pos
unsigned	len
unsigned	copied
struct page *	page
void *	fsdata

inode等于host

2136

start等于pos按位与PAGE_SIZE减1

2138

如果此条件成立可能性小(为编译器优化)(copied < len)则

2151

如果非PageUptodate(page)则copied等于0

2154

If a page has any new buffers, zero them out here, and mark them uptodate* and dirty so they'll be written out (in order to prevent uninitialised* block data from leaking). And clear the new bit.

2156

flush_dcache_page(page)

2159

__block_commit_write(inode, page, start, start + copied)

2161

返回:copied
