Does this include the changes to all those PCMCIA net drivers which
Jeff has had for a while from me?

I'd like to get those patches into mainline so I can close bugme bug
1711, but I think Jeff's waiting for responses from the individual
net driver maintainers first. ;(

Nope, was just waiting for 2.6.2 to be released.  The first post-262 
batch has been merged, am now sending the second batch.  Yours is in the 
third batch :)

Nikita's vm-dont-rotate-active-list.patch still has this:

+/* dummy pages used to scan active lists */
+static struct page scan_pages[MAX_NUMNODES][MAX_NR_ZONES];
+

Which probably needs its nodes and cachelines untangled.
Maybe it doesn't - I really don't know.

The idle toad's way is to shove it in the pgdat.
Maybe even the zone structure?

It logically belongs in the zone structure, but apparently
dependancies will not allow that right now.

Nice.  This patch contains some AIO/DIO race fixes.

The nit warnings that sprung up in the defconfig builds are...

Hmm..that defeats the purpose of making it generic. :(

I was able to build w/o PCI for an SA1100 platform, so I'm assuming 
this is an x86 issue.  I'll dig into it when I get some free time.
I only have x86 and arm toolchains, so can folks on other non-PCI
architectures remove the dmapool-needs-pci.patch and try building 
w/o PCI.

I agree.  I think the comment was that UML didn't build properly, but I
really don't see what the error would be.

Could the original submitter of this patch please send us the error
messages that this patch is supposed to fix?

Andrew,

I tested 2.6.2-mm1 on an 8-proc running 6 copies of the read_under
test and all 6 read_under tests saw uninitialized data in less than 5
minutes. :(

Daniel,

Same here... Just FYI, I am running with your original patch and
not failed so far (2 hours..) Normally, I see the problem in 15 min or so.

Thanks,

The performance implications of synchronising behind kjournald writes for
normal non-blocking writeback are bad.  Can you detail what you now think
is the failure mechanism?

I think the problem is that any block_write_full_page(WB_SYNC_NONE)
that hits a page that has a buffer in process of being written will
get PageWriteback cleared even though the i/o has not completed.
(The buffer will be locked, but buffer_dirty() is cleared, so
 __block_write_full_page() will SetPageWriteback(); unlock_page();
 see no buffer were submitted and call end_page_writeback())

Any subsequent filemap_write_and_wait() or filemap_fdatawrite() /
filemap_fdatawait will never wait for that i/o.  So this could
potentially be a problem for more than just DIO.

BTW: 2.4 __block_write_full_page() always did a lock_buffer(), so
it waits for i/o in flight.

I agree though, it would be best if non-sync __block_write_full_page()
would not block on buffers in flight.  Somehow we need to move the
clearing of PageWriteback() until after the buffer has been written
even for the case where ll_rw_block() is called.

Thoughts?

Daniel

Re: 2.6.2-mm1 aka "Geriatric Wombat" DIO read race still fails

[Daniel McNeil]

I patched 2.6.2-mm1 with the wait_on_buffer(bh) in
__block_write_full_page() and my tests ran overnight and
though today without any errors.

I'm looking to see if there is any way to move the end_page_writeback()
for this locked bh case to the end_buffer_write_sync().  Kind of
tricky...

Daniel
