<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I have been chasing down the way the inode and page caches
are structured and handled, but there is a mystery I have not been able to
track down yet. How does the I/O queue that dirty inodes and pages are put
into when it’s time to flush them out to disk get picked up? Also, where
are the sources for the I/O schedulers? I haven’t been able to locate
them yet either.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I know this should not be too hard to locate, but it seems
as though there’s some magic involved when the inode/page gets put in the
i/o queue and then <something happens here> and the i/o is scheduled and,
eventually, performed.<o:p></o:p></span></font></p>
