The vm part in particular is right now getting stressed on a 16G box kindly
provided by osdlab.org and it didn't exibith any problem yet. This is a trace
of the workload that is running on the machine overnight.

It seems still very responsive despite of the load (and also despite being at
the other side of the Atlantic :).

If it swaps too much please try:

echo 6 > /proc/sys/vm/vm_scan_ratio
echo 2 > /proc/sys/vm/vm_mapped_ratio
echo 4 > /proc/sys/vm/vm_balance_ratio

Thanks!

Only in 2.4.13pre3aa1: 00_highmem-deadlock-1 Only in 2.4.13pre5aa1: 00_highmem-deadlock-2

Rediffed so that it's self contained (previously it wasn't very readable).

Only in 2.4.13pre3aa1: 00_lowlatency-fixes-1 Only in 2.4.13pre5aa1: 00_lowlatency-fixes-2

Added a reschedule point, mainly for madvise but it's in the ->nopage way too.

Only in 2.4.13pre3aa1: 00_seg-reload-1

Dropped, the common case is user<->kernel, and it have to be very fast too since it's more important. (idling routers would better not use irq at all but to dedicate a cpu to the polling work)

Only in 2.4.13pre3aa1: 00_vm-3 Only in 2.4.13pre3aa1: 00_vm-3.2 Only in 2.4.13pre5aa1: 10_vm-4

Further vm work. Not sure if this is better than the previous one, but now the few magic numbers are sysctl configurable. Included many fixes from Linus (that are also in pre5 of course) and one fix from Manfred to avoid interrupt to eat the pfmemalloc reserved pool.

Only in 2.4.13pre3aa1: 10_highmem-debug-5 Only in 2.4.13pre5aa1: 20_highmem-debug-6

Fixed zone alignment to avoid crashes when highmem emulation is enabled.

Dropped sync_dev from blkdev ->close to avoid a deadlock on lvm close(2), fix from Alexander Viro.
