mapping_set

函数名称：mapping_set_error - record a writeback error in the address_space*@mapping - the mapping in which an error should be set*@error - the error to set in the mapping* When writeback fails in some way, we must record that error so that

函数原型：static inline void mapping_set_error(struct address_space *mapping, int error)

返回类型：void

struct address_space *	mapping
int	error

**调用者**
名称	描述
page_endio	After completing I/O on a page, call this routine to update the page* flags appropriately
__writepage	Function used by generic_writepages to call the real writepage* function and set the mapping flags on error
handle_write_error	We detected a synchronous write error writing a page out. Probably* -ENOSPC. We need to propagate that into the address_space for a subsequent* fsync(), msync() or close().* The tricky part is that after writepage we cannot touch the mapping: nothing
me_pagecache_dirty	Dirty pagecache page* Issues: when the error hit a hole page the error is not properly* propagated.
mark_buffer_write_io_error
__block_write_full_page	While block_write_full_page is writing back the dirty buffers under* the page lock, whoever dirtied the buffers may decide to clean them* again at any time
__mpage_writepage
dax_writeback_mapping_range	Flush the mapping to the persistent domain within the byte range of [start,* end]. This is required by data integrity operations to ensure file data is* on persistent storage prior to completion of the operation.
iomap_finish_page_writeback
iomap_writepage_map	We implement an immediate ioend submission policy here to avoid needing to* chain multiple ioends and hence nest mempool allocations which can violate* forward progress guarantees we need to provide
