set_page_dirty_lock | set_page_dirty() is racy if the caller has no reference against* CPU could truncate the page off the mapping and then free the mapping.* Usually, the page _is_ locked, or the caller is a user-space process which |
clear_page_dirty_for_io | Clear a page's dirty flag, while caring for dirty memory accounting.* Returns true if the page was previously dirty.* This is for preparing to put the page under writeout. We leave the page* tagged as dirty in the xarray so that a concurrent write-for-sync |
pagecache_isize_extended | pagecache_isize_extended - update pagecache after extension of i_size*@inode: inode for which i_size was extended*@from: original inode size*@to: new inode size* Handle extension of inode size either caused by extending truncate or by |
follow_page_pte | |
zap_pte_range | |
fault_dirty_shared_page | Handle dirtying of a page in shared file mapping on a write fault.* The function expects the page to be locked and unlocks it. |
try_to_unmap_one | @arg: enum ttu_flags will be passed to this argument |
end_swap_bio_write | |
__swap_writepage | |
add_to_swap | add_to_swap - allocate swap space for a page*@page: page we want to move to swap* Allocate swap space for the page and add the page to the* swap cache. Caller needs to hold the page lock. |
