This my diff includes:
o My fully jiffy wrap compliant schedule_timeout() and
interruptible_sleep_on_timeout(). My drivers are all uptodate
with these new functions, other drivers can not compile. I had
not the time to update other hardare too. Notify me if something
doesn't compile and I' ll sent you an incremental patch ASAP.
o Tons of time_*() jiffies updates. Also some fix for some timer
that it' s been set to `0' in order to run ASAP. When a timer
has to be run ASAP should be set with expires = jiffies instead.
o My latest (>oom-22) memory management OOM fix. With this code
kswapd is really a daemon an run in background and schedule as a
normal process but with dynamic priority. I also tried to shutdown
kswapd (incidentally btw ;-) and all my evil process didn' t
segfaulted. kswapd is useful to improve things but with this patch
__get_free_pages/try_to_free_pages() are able to handle the
swapping just fine without need kswapd (and this is a must
for RT tasks). As just said kswapd improve a _lot_ (because
async) the time needed for the swapout. The new FP_IMPOSSIBLE
flag make __get_free_pages() able to detect when to OOM fine.
Also swapoff -a works just fine. You could get some warning
message from the swap code but I have verifyed that it' s not
a race, but it' s a normal allowed and safe case when while
swapoff is swapping-in, also the process has swapped in the
page before swapoff had the time to swap_duplicate().
o mmap sync fix. This patch allow to share an mmapped region and
to update the shared mappings at sync/release time for all process
that are sharing such memory region. This improve things a lot.
I don' t know if it' s enough generic (because I handle only
the filemap case), but it' s been rock so far and looks clean.
o proc/sysctl #ifdef fix. This will allow you to compile
your kernel without /proc and/or sysctl support.
o little vmalloc fix.
o swap_cache_find_success/total now say something.
I hope to have not missed something ;->.
Everything in the patch worked fine here so far.
Note that when you' ll boot your new kernel you' ll run in the past for 1
hour (run uptime and you' ll see), so you' ll have exactly 1 hour to
stress test the kernel to eventually catch some nasty timer expire bug. I
had no one problem so far also while in the past though...

Linus tell me if you are interested on something, in such case I'll
extract it from my tree.
