10 years ago[PATCH] Copy XFS readdir hack into nfsd code.
David Woodhouse [Thu, 31 Jul 2008 19:29:12 +0000]
[PATCH] Copy XFS readdir hack into nfsd code.

Some file systems with their own internal locking have problems with the
way that nfsd calls the ->lookup() method from within a filldir function
called from their ->readdir() method. The recursion back into the file
system code can cause deadlock.

XFS has a fairly hackish solution to this which involves doing the
readdir() into a locally-allocated buffer, then going back through it
calling the filldir function afterwards. It's not ideal, but it works.

It's particularly suboptimal because XFS does this for local file
systems too, where it's completely unnecessary.

Copy this hack into the NFS code where it can be used only for NFS
export. In response to feedback, use it unconditionally rather than only
for the affected file systems.

Merge branch 'genirq-v28-for-linus' of git://git./linux/kernel/git/tip/linux-2.6-tip

This merges branches irq/genirq, irq/sparseirq-v4, timers/hpet-percpu
and x86/uv.

The sparseirq branch is just preliminary groundwork: no sparse IRQs are
actually implemented by this tree anymore - just the new APIs are added
while keeping the old way intact as well (the new APIs map 1:1 to
irq_desc[]).  The 'real' sparse IRQ support will then be a relatively
small patch ontop of this - with a v2.6.29 merge target.

PCI: introduce an pci_ioremap(pdev, barnr) function

A common thing in many PCI drivers is to ioremap() an entire bar.  This
is a slightly fragile thing right now, needing both an address and a
size, and many driver writers do.. various things there.

This patch introduces an pci_ioremap() function taking just a PCI device
struct and the bar number as arguments, and figures this all out itself,
in one place.  In addition, we can add various sanity checks to this
function (the patch already checks to make sure that the bar in question
really is a MEM bar; few to no drivers do that sort of thing).

Hopefully with this type of API we get less chance of mistakes in
drivers with ioremap() operations.

Roland Dreier [Mon, 22 Sep 2008 21:55:24 +0000]
PCI: fix MSI-HOWTO.txt info about MSI-X MMIO space

The current MSI-HOWTO.txt says that device drivers should not request the
memory space that contains MSI-X tables.  This is because the original
MSI-X implementation did a request_mem_region() on this space, but that
code was removed long ago (in the pre-git era, in fact).  Years after the
code was changed, we might as well clean up the documention to avoid a
confusing mention of requesting regions: drivers using MSI-X can just use
pci_request_regions() just like any other driver, and so there's no need
for MSI-HOWTO.txt to talk about this at all.

Alex Chiang [Tue, 2 Sep 2008 15:40:51 +0000]
PCI: connect struct pci_dev to struct pci_slot

The introduction of struct pci_slot (f46753c5e354b857b20ab8e0fe7b25)
added a struct pci_slot pointer to struct pci_dev, but we forgot to
associate the two.

Connect the two structs together; the interesting portions of the object
lifetimes are:

- when a new pci_slot is created, connect it to the appropriate
  pci_dev's. A single pci_slot may be associated with multiple
  pci_dev's, e.g. any multi-function PCI device.

- when a pci_slot is released, look for all the pci_dev's it was
  associated with, and set their pci_slot pointers to NULL

- when a pci_dev is created, look for slots to associate with.

Note -- when a pci_dev is released, we don't need to do any bookkeeping,
since pci_slot's do not have pointers to pci_dev's.

Rafael J. Wysocki [Mon, 18 Aug 2008 19:38:00 +0000]
PCI PM: Introduce function pci_wake_from_d3

Many device drivers use the following sequence of statements to enable
the device to wake up the system while being in the D3_hot or D3_cold
low power state:

        pci_enable_wake(pdev, PCI_D3hot, 1);
        pci_enable_wake(pdev, PCI_D3cold, 1);

However, the second call is not necessary if the first one succeeds (the
ordering of the statements above doesn't matter here) and it may even be
harmful, because we are not supposed to enable PME# after the wake-up
power has been enabled for the device.

To allow drivers to overcome this problem, introduce function
pci_wake_from_d3() that will enable the device to wake up the system
from any of D3_hot and D3_cold as long as the wake-up from at least one
of them is supported.

PCI: remove dynids.use_driver_data

The driver flag dynids.use_driver_data is almost consistently not set,
and causes more problems than it solves.  It was initially intended as a
flag to indicate whether a driver's usage of driver_data had been
carefully inspected and was ready for values from userspace.  That audit
was never done, so most drivers just get a 0 for driver_data when new
IDs are added from userspace via sysfs.  So remove the flag, allowing
drivers to see the data directly (a followon patch validates the passed
driver_data value against what the drivers expect).
