After a bus reset, let nodemgr call high-level update hooks first for nodes
which do not need to be probed. The main benefit is for a bus with more
than one SBP-2 device: SBP-2 reconnects will be performed before SBP-2
logins, thus have a much higher chance to succeed, and their SCSI devices
will not be blocked much longer than necessary. This was demonstrated for
Linux 2.4 by Dave Cinege a while ago.
A better approach would be to perform time-consuming probes in parallel by a
subthread. I actually plan to implement this for sbp2 but it may take a
while to get that done and tested. Until then, this tweak is a huge
improvement for users with multiple SBP-2 devices.

Some old 1394-1995 SBP-2 bridges would hang if they received a broadcast write
request to BROADCAST_CHANNEL before the config ROM was read. Affected devices
include Datafab MD2-FW2 2.5" HDD and SmartDisk VST FWCDRW-V8 portable CD writer.
The write request is now directed to specific nodes instead of being broadcast
to all nodes at once, and it is only performed if a previous read request at
this register succeeded.

Hey, for no other reason than the fact that I'll be off-line for a
week.
Of course, I could force everybody to just use git (and when I'm emperor
of the world, don't think I won't!), but it seems some people want to
just test official releases. Even if they are just -rc's.
By the time I'm back, Andrew will have fixed all my bugs, and I'll
release it as 2.6.15 and take all the credit.

We want to link the "regular" SCSI drivers before the USB storage
driver, since historically we've always detected internal SCSI disks
before the external USB storage modules.
The link order matters for initcall ordering, and this got broken by
mistake by commit 7586269c0b which moved
the USB host controller PCI quirk handling around.

Doing the following:
1. On server:

$ until grep -q foo t/tmp ; do echo -n . ; sleep 1 ; done
3. On server, create a *new* file with the same name containing that
string:
$ mv ~/t/tmp ~/t/tmp.old; echo foo > ~/t/tmp
will show how the client will never (and I mean never ;-) ) see
the updated file.
The problem is that we do not update nfsi->cache_change_attribute when the
file changes on the server (we only update it when our client makes the
changes). This again means that functions like nfs_check_verifier() will
fail to register when the parent directory has changed and should trigger
a dentry lookup revalidation.

As explained at:
http://www.cs.ucsb.edu/~krishna/igmp_dos/
With IGMP version 1 and 2 it is possible to inject a unicast
report to a client which will make it ignore multicast
reports sent later by the router.
The fix is to only accept the report if is was sent to a
multicast or unicast address.

Commit 64c7c8f885 broke the ACPI C2 and C3
sleep states, because it left TIF_POLLING_NRFLAG active even though
those states do not actually poll the reschedule flag at all. As a
result, the CPU wouldn't get sent an IPI when it was to be woken up, and
would only notice that it had runnable processes on the next timer tick.

2.6.15-rc1 made sg's st_unmap_user_pages and st's sgl_unmap_user_pages
BUG on a PageReserved page. But that's wrong: they could be unmapping
the ZERO_PAGE, which is marked PG_reserved; and perhaps others (while
get_user_pages is still permitted on VM_PFNMAP areas - that may change).
More change is needed here: sg claims to dirty even pages written from,
and st claims not to dirty even pages read into; and SetPageDirty is not
adequate for this nowadays. Fixes to those follow in a later patch: for
the moment just fix the 2.6.15 regression.
