You probably meant "Thimkpads".

Hi !

Wow.
I'd heard that there was a way to set 3.5/0.5 GiB split, and that there
was a patch that removed the split and isolated the kernel (but that was
slow), so I was just curious about all this stuff with people screaming
about how tight 4G of VM is

You can insert the module in a running kernel and after barking as
follows (once for each disk attached) it runs just fine.
Basically nobody has ever had hardware to test sata_vsc with that

No SMP protection on the SBOX, better look into that.
The locking you'll likely need to add will make this
routine serialize many networking

This patch extracts all the interesting pieces for handling rss and
anon_rss into definitions in include/linux/sched.h. All rss operations
are performed through the following three macros:
get_mm_counter(mm, member) -> Obtain the value of a counter
set_mm_counter(mm, member, value)
The page fault handler attempts to use the page_table_lock only for short
time periods. It repeatedly drops and reacquires the lock. When the lock
is reacquired, checks are made if the underlying pte has changed before
replacing the pte value. These locations are a good fit for the use of
Hi,
Attached the new patch following Arjan's recommendations.
I'm sorry about not making it "inlined", but my mail agent messes up the
diffs if I do so.
Still waiting for the OSDL STP tests results, they will take a while to
finish.
Cheers,

Do not use the page_table_lock in do_anonymous_page. This will significantly
increase the parallelism in the page fault handler in SMP systems. The patch
also modifies the definitions of _mm_counter functions so that rss and anon_rss
become atomic.
