**调用者**
名称	描述
buffer_check_dirty_writeback	Returns if the page has dirty or writeback buffers. If all the buffers* are unlocked and clean then the PageDirty information is stale. If* any of the pages are locked, it is assumed they are locked for IO.
write_boundary_block	Called when we've recently written block `bblock', and it is known that* `bblock' was for a buffer_boundary() buffer. This means that the block at* `bblock + 1' is probably a dirty indirect block. Hunt it down and, if it's* dirty, schedule it for IO
fsync_buffers_list
remove_inode_buffers	Remove any clean buffers from the inode's buffer list. This is called* when we're trying to free the inode itself. Those buffers can pin it.* Returns true if all buffers were removed.
mark_buffer_dirty	mark_buffer_dirty - mark a buffer_head as needing writeout@bh: the buffer_head to mark dirty mark_buffer_dirty() will set the dirty bit against the buffer, then set* its backing page dirty, then tag the page as dirty in the page cache* and then attach
__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
