+I've yet to find any desktop workload that benefits from anything higher than
+a swappiness as low as possible. Unfortunately setting it to zero can rarely
+lead to unexplained stalls in the VM so use 10.

+Add a background scanning timer to restore the watermarks to the pages_lots
+level and only call on it if kswapd has not been called upon for the last 5
+seconds. This allows us to balance all zones to the more generous pages_lots
+watermark at a time unrelated to page allocation thus leading to lighter
+levels of vm load when called upon under page allocation.

+Signed-off-by: Con Kolivas <kernel@kolivas.org>
+
+The -ck patches modify mm/vmscan.c and add a timer to wake up kswapd every 5 
+seconds. This timer is initialized after the creation of the kswapd thread.
+
+The kswapd() thread function calls mod_timer at the front of its infinite 
+service loop (to reset the timer to 5 seconds in the future). mod_timer() 
+includes a BUG_ON() to assert that the timer's callback function is set.
+
+Since the wakeup timer is initialized after the kswapd thread is created, if 
+kswapd gets scheduled before kswapd_run() has prepared the timer, the 
+BUG_ON() check will throw a stack trace and immediately terminate the kswapd 
+thread.
+
+This patch modifies the kswapd_run() function in mm/vmscan.c to initialize the 
+watermark timer before starting the kswapd thread.

@@ -0,0 +1,45 @@
+The default dirty ratio is chosen to be a compromise between throughput and
+overall system latency. On a desktop, if an application writes to disk a lot,
+that application should be the one to slow down rather than the desktop as a
+whole. At higher dirty ratio settings, an application could write a lot to
+disk and then happily use lots of CPU time after that while the rest of the
+system is busy waiting on that naughty application's disk writes to complete
+before anything else happening.
+
+Lower ratios mean that the application that do a lot of disk writes end up
+being responsible for their own actions and they're the ones that slow down
+rather than the system in general.
+
+This does decrease overall write throughput, but to the benefit of the latency
+of the system as a whole with disk writes.
+
+Other checks may well round this up to 10 still at startup.
