NFSD forgets to call mnt_drop_write after a successful rename. Here's a

One thing I wasn't sure is whether I could move the mnt_drop_write line a

Change the semantics of pci_create_slot() such that it does not
require a hotplug release() method when creating a slot. Now, we
can use this interface to create a pci_slot for any physical PCI
slots, not just hotpluggable ones.
Add new pci_slot_add_hotplug() interface so that various PCI
Detect all physical PCI slots as described by ACPI, and create
entries in /sys/bus/pci/slots/.
Not all physical slots are hotpluggable, and the acpiphp module
does not detect them. Now we know the physical PCI geography of
our system, without caring about hotplug.

I'm not very happy with hint #2. I struggled with ways to express it
and finally decided to ship it^W^W release early/release often. :)
Suggestions welcome.

Add a section on kconfig hints: how to do in Kconfig files.
Fix a few typos/spellos.
Introduce struct pci_slot
- Make pci_slot the primary sysfs entity. hotplug_slot becomes a
subsidiary structure.
- Change the prototype of pci_hp_register() to take the bus and
slot number (on parent bus) as parameters.
- Remove all the ->get_address methods since this functionality

Register one slot per slot, rather than one slot per function.
Change the name of the slot to fake%d instead of the pci address.

Rename the slot to be the contents of the 'path' sysfs attribute, and
delete the attribute. The mapping from pci address to slot name is
supposed to be done through

The *real* fix for this is almost certainly to just get rid of the 64-bit

That would likely break the ABI. x86-64 ABI is completely different here --
no ibcs, just pure x86 ISA.

2.6.23.1. It had been running at 2.6.20. I moved to the new kernel via
"make oldconfig" -- choosing defaults. That didn't work.
To narrow things down I tried it under 2.6.21.1 (made

Use sparsemem as the only memory model for UP, SMP and NUMA.
Measurements indicate that DISCONTIGMEM has a higher
overhead than sparsemem. And FLATMEMs benefits are minimal. So I think its
best to simply standardize on sparsemem.

While a signal is blocked, it must be posted even if its action is
SIG_IGN or is SIG_DFL with the default action to ignore. This works
right most of the time, but is broken when a sigwait (rt_sigtimedwait)
