- Linus has merged ia32 NUMA discontigmem support
+ Added a little cleanup patch from various folks.
Threw in the kichen sink:
+writeback-control.patch
Infrastructure for richer communication between the block layer and the VM.
+queue-congestion.patch
Infrastructure for non-blocking writeout in the block layer.
+nonblocking-pdflush.patch
Non-blocking background writeback
+nonblocking-vm.patch
Non-blocking page reclaim.
This is all about reducing latency when the machine is performing heavy writeback, which has been a significant performance problem for ever. The code also happens to provide improved scalability in many-spindle pagecache writeback.
The code is stable, but by no means complete. Under some loads it will chew tons of CPU in page reclaim.
But with mem=512m and four instances of `dbench 100' each against a different disk the machine was 100% responsive and ran a `make -j6 bzImage' in three minutes. Without these patches the kernel took over five minutes just to unpack the kernel tarball.
