const struct buffer_head * | bh |
Name | Describe |
---|---|
__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 |
page_zero_new_buffers | 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. |
__block_write_begin_int | |
nobh_write_begin | On entry, the page is fully not uptodate.* On exit the page is fully uptodate in the areas outside (from,to)* The filesystem needs to handle block truncation upon failure. |
dio_zero_block | If we are not writing the entire block and get_block() allocated* the block for us, we need to fill-in the unused portion of the* block with zeros |
do_direct_IO | Walk the user pages, and the file, mapping blocks to disk and generating* a sequence of (page,offset,len,block) mappings. These mappings are injected* into submit_page_section(), which takes care of the next stage of submission |
