I'm not sure about this. I don't think that NODELAY option hurts
performance. However, open-iscsi does not use MSG_MORE properly with
sendpage, so NODELAY option hurts the open-iscsi performance.
I've attached a patch to fix NODELAY and MSG_MORE problems and the
write performance results with disktest.
I use Opteron boxes connected directly, Chelsio NICs, 1500-byte MTU,
64 KB I/O size, and the iSCSI parameters on open-iscsi web site.
With only NODELAY fix, the performance drops, as you said. On the
other hand, NODELAY and MSG_MORE fixes improve the performance
overall.

Now it looks like we'll have multiple users of the iscsi transport

patch moves iscsi to being an initiator in its own right which selects

The problem is that klists claim to provide semantics for safe traversal of
lists which are being modified. The failure case is when traversal of a
list causes element removal (a fairly common case). The issue is that
although the list node is refcounted, if it is embedded in an object (which
is universally the case), then the object will be freed regardless of the
klist refcount leading to slab corruption because the klist iterator refers
to the prior element to get the next.
The solution is to make the klist take and release references to the
embedding object meaning that the embedding object won't be released until
the list relinquishes the reference to it.
(akpm: fast-track this because it's needed for the 2.6.13 scsi merge)

Sanitized and fixed floppy dependencies: split the messy dependencies for
BLK_DEV_FD by introducing a new symbol (ARCH_MAY_HAVE_PC_FDC), making
BLK_DEV_FD depend on that one and taking declarations of ARCH_MAY_HAVE_PC_FDC
to arch/*/Kconfig. While we are at it, fixed several obvious cases when
BLK_DEV_FD should have been excluded (architectures lacking asm/floppy.h
are *not* going to have floppy.c compile, let alone work).
If you can come up with better name for that ("this architecture might
have working PC-compatible floppy disk controller"), you are more than
welcome - just s/ARCH_MAY_HAVE_PC_FDC/your_prefered_name/g in the patch
below...

Most of the patch is whitespace cleanup, but more importantly, this patch
checks to see whether a callback is set before calling it. On cx88 boards
(currently the only boards using lgdt330x in 2.6.13) every callback is set.
However, newer drivers currently in development leave a callback undefined,
and lgdt330x must not call it if it isn't defined.

Patrick Keene wrote to the linux-dvb list, asking where in menuconfig he
can enable dvb-bt8xx for his AVerMedia DVB card. I pointed the following
out to him:
config DVB_BT8XX
tristate "Nebula/Pinnacle PCTV/Twinhan PCI cards"
It has been agreed upon that this description is extremely misleading.
This patch changes the one-liner description text of dvb-bt8xx to something
more meaningful, and adds AVerMedia to the detailed description.

I noticed a strange return value in smsc_ircc_init in
drivers/net/irda/smsc_ircc2.c in rc4-mm1.
When reaching the line "if (ircc_fir > 0 && ircc_sir > 0)", ret is 0. So I
don't see the point of setting it to 0 in the "else" case. >From what I
see in 2.6.12 it should probably be set to -ENODEV at the begining of the
"else" case. The attached patch does this.

The code w100fb was based on was horribly Sharp SL-C7x0 specific and there
was little else that could be done as I had no access to anything else with
a w100 in it. There is no real documentation about this chipset available.
Ian Molton has access to other platforms with the w100 (Toshiba e-series)
and so between us, we've improved w100fb and made it platform independent.
Ian Molton also added support for the very similar w3220 and w3200
chipsets.
There are a lot of changes here and it nearly amounts to a rewrite of the
driver but it has been extensively tested and is being used in preference
to the original driver in the Zaurus community. I'd therefore like to
update the mainline code to reflect this.
