Look in the linux/Documentation directory of the "kernel-source" RPM
for the file "/usr/src/linux-2.4/Documentation/sysctl/vm.txt". There
is a file, "/proc/sys/vm/bdflush", that lets you control when the
block cache gets flushed, how much is flushed at once, and so on.
Also Google for "/proc/sys/vm/bdflush".
