Christoph Hellwig [Thu, 31 May 2007 18:12:26 +0000]
[SCSI] introduce shost_priv helper

Currently accessing the scsi host private data is rather messy because
it comes as an unsigned long that always needs a cast first.  This patch
introduces a helper that does the cast called shost_priv.  It's similar
in spirit to netdev_priv for network drivers.

This is the first patch introducing the macro, and the second patch
in the series will convert esp and it's subdrivers as an example.
Further conversion will wait until the helper is in the tree to make
patch juggling easier.

This restores the previously removed netif_poll_enable call in e1000_open.
It's needed on all but the first call to e1000_open for a NIC as
e1000_close always calls netif_poll_disable.

netif_poll_enable can only be called safely if no polls have been
scheduled.  This should be the case as long as we don't enter our IRQ
handler.

[SCSI] gdth: fix ambiguous gdthtable definition

Labeling a variable as __attribute_used__ is ambiguous: it means
__attribute__((unused)) for gcc <3.4 and __attribute__((used)) for gcc >=3.4.
There is no such thing as labeling a variable as __attribute__((used)).  We

NOHZ: prevent multiplication overflow - stop timer for huge timeouts

get_next_timer_interrupt() returns a delta of (LONG_MAX > 1) in case
there is no timer pending. On 64 bit machines this results in a
multiplication overflow in tick_nohz_stop_sched_tick().

Reported by: Dave Miller <davem@davemloft.net>

Make the return value a constant and limit the return value to a 32 bit
value.

When the max timeout value is returned, we can safely stop the tick
timer device. The max jiffies delta results in a 12 days timeout for
HZ=1000.

In the long term the get_next_timer_interrupt() code needs to be
reworked to return ktime instead of jiffies, but we have to wait until
the last users of the original NO_IDLE_HZ code are converted.

IPoIB/cm: Fix performance regression on Mellanox

commit 518b1646 ("IPoIB/cm: Fix SRQ WR leak") introduced a severe
performance regression on Mellanox cards, because keeping a QP in the
error state for extended periods of time moves hardware to the slow
path (until the QP is destroyed).  For example, MPI latency goes from
~3 usecs to ~7 usecs.

Fix this by posting a send WR on one of the QPs that are being
flushed, instead of using a separate drain QP that is kept in the
error state.

This fixes bug <https://bugs.openfabrics.org/show_bug.cgi?id=636>,

CQEs with error can be chained together even if the RQ is part of SRQ,

12 years agoUSB: replace flush_workqueue with cancel_sync_work
Alan Stern [Tue, 29 May 2007 20:34:52 +0000]
USB: replace flush_workqueue with cancel_sync_work

This patch (as912) replaces a couple of calls to flush_workqueue()
with cancel_sync_work() and cancel_rearming_delayed_work().  Using a
more directed approach allows us to avoid some nasty deadlocks.  The
prime example occurs when a first-level device (the parent is a root
hub) is removed while at the same time the root hub gets a remote
wakeup request.  khubd would try to flush the autosuspend workqueue
while holding the root-hub's lock, and the remote-wakeup workqueue
routine would be waiting to lock the root hub.

The patch also reorganizes the power management portion of
usb_disconnect(), separating it out into its own routine.  The
autosuspend workqueue entry is cancelled immediately instead of
waiting for the device's release routine.  In addition,
synchronization with the autosuspend thread is carried out even for
root hubs (an oversight in the original code).

The Linux kernel ignored the PROM's serial settings (115200,n,8,1 in

[SPARC64]: Eliminate NR_CPUS limitations.

Cheetah systems can have cpuids as large as 1023, although physical
systems don't have that many cpus.

Only three limitations existed in the kernel preventing arbitrary
NR_CPUS values:

1) dcache dirty cpu state stored in page->flags on
   D-cache aliasing platforms.  With some build time
   calculations and some build-time BUG checks on
   page->flags layout, this one was easily solved.

2) The cheetah XCALL delivery code could only handle
   a cpumask with up to 32 cpus set.  Some simple looping
   logic clears that up too.

3) thread_info->cpu was a u8, easily changed to a u16.

There are a few spots in the kernel that still put NR_CPUS
sized arrays on the kernel stack, but that's not a sparc64
specific problem.

Fix this warning on x86-64

drivers/firewire/fw-cdev.c:798: warning: initialization from incompatible pointer type

by making the return code of ioctl_send_request() the same as all the
other ioctl_xxx() return codes.

12 years agofirewire: prefix modules with firewire- instead of fw-

firewire: prefix modules with firewire- instead of fw-

Of course everybody immediately associates "fw-" with FireWire, not
firmware or firewall or whatever.  But "firewire-" has a nice ring to
it too.

ieee1394: raw1394: Fix async send

While playing with libiec61883 I've noticed that async_send is broken
because it was doing copy_from_user(...., packet->data_size) before
packet->data_size was set to any useful value.  It got broken when
packet->allocated_data_size got introduced, as hpsb_alloc_packet does
not set packet->data_size anymore.  (Regression in 2.6.22-rc1)

12 years agoieee1394: eth1394: bring back a parent device
Stefan Richter [Sun, 20 May 2007 23:05:41 +0000]
ieee1394: eth1394: bring back a parent device

This adds a real parent device to eth1394's ethX device like in Linux
2.6.20 and older.  However, due to unfinished conversion of the ieee1394
away from class_device, we now refer to the FireWire controller's PCI
device as the parent, not to the ieee1394 driver's fw-host device.

Having a real parent device instead of a virtual one allows udev scripts
to distinguish eth1394 interfaces from networking bridges, bondings and
the likes.

Fixes a regression since 2.6.21:
