Is there any chance that this patchset could go into mm now? This has been
discussed since last August
Changelog:
V17-V18 Rediff against 2.6.11-rc5-bk4
V16-V17 Do not increment page_count in do_wp_page. Performance data
posted.
V15-V16 of this patch: Redesign to allow full backback
The current way of updating ptes in the Linux vm includes first clearing
a pte before setting it to another value. The clearing is performed while
holding the page_table_lock to insure that the entry will not be modified
by the CPU directly (clearing the pte clears the present bit),
by an arch
This patch extracts all the operations on 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) - Set the value of a
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.

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
Just a thought - perhaps you could see if Jay can test the performance
scaling of these changes on larger systems (8 to 64 CPUs, give or take,
small for SGI, but big for some vendors.)
Things like a global lock, for example, might be harmless on smaller
systems, but hurt big time on bigger

This way we actually share dentries before inodes and thus mark more
inodes reclaimable once we shake them.

I can't use sockfd_put(sock) directly.
I trace its code, the code is
extern __inline__ void sockfd_put(struct socket *sock)
{
fput(sock-file);
}
so I use fput(sock-file)
but it has problems too
1) execute ls in the ftp is also block
2) kernel prints socki_lookup: socket file changed!

Hi everybody, I just joined the LKML!
Don't worry, this is not just a test message, I do actually have
something to say. I just compiled 2.6.11-rc5-mm1 and got undefined
symbols match_int, match_octal, match_token, and match_strdup in
several modules. This is using binutils 2.15 and gcc 3.4.4

Can you explain what you mean

Yes but it seems that you've assumed that ioctl == flagged taskfile

The names should have pci in them.
I don't like ioerr_clear because it implies we are clearing the io error; we are not; we are clearing the checker
for io errors.

It seems to me that if in the amd8111e_open() fuction dev-irq isn't
zero and the irq request succeeds it might not get released anymore.
Specifically, on failure of the amd8111e_restart() call the function
returns -ENOMEM without releasing the irq. The

Hi,
It seems to me that in the VIA Rhine device driver the requested irq might
not be freed in case the alloc_ring() function fails. alloc_ring()
can fail with a ENOMEM return value because of possible
pci_alloc_consistent() failures.
This patch applies to 2.6.11-rc5-bk2.
If I had to guess, I would try the attached patch. The via82cxxx.c
driver is a bit annoying in that, here we do not talk to the ISA bridge
but to the PCI device 0x4149 itself.
If this doesn't work, I could probably whip together a quick PATA driver
for libata that works on this hardware.

You really don't want -2 for the file mode in sysfs. It creates:

on my box. Here's a fix against a clean 2.6.11-rc5 kernel, please
