We mark it dirty unconditionally, but move it onto the 14 dirty list only if it is hashed or if it refers to a blockdev. 15 If it was not hashed, it will never be added to the dirty list 16 even if it is later hashed, as it will have been marked dirty already. 17 </p><p> 18 19 In short, make sure you hash any inodes _before_ you start marking 20 them dirty. 21 </p><p> 22 23 Note that for blockdevs, inode->dirtied_when represents the dirtying time of 24 the block-special inode (/dev/hda1) itself. And the ->dirtied_when field of 25 the kernel-internal blockdev inode represents the dirtying time of the 26 blockdev's pages. This is why for I_DIRTY_PAGES we always use 27 page->mapping->host, so the page-dirtying time is recorded in the internal 28 blockdev inode. 29</p></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="API-inode-congested.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="other_functions.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="API-writeback-inodes-sb-nr.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top"><span class="phrase">inode_congested</span> </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> <span class="phrase">writeback_inodes_sb_nr</span></td></tr></table></div></body></html> 30
