From: Greg KH
Subject: [GIT PATCH] driver core patches for .36
Date: Thursday, August 5, 2010 - 2:33 pm

Here's the big driver core merge for the .36 merge window.

Nothing major here, lot of little things around the driver-core
area.  Biggest is the firmware code rework to make things simpler and
the addition of a stable place to mount cgroupfs that everyone has
now agreed on (acked by the cgroup maintainers.)

Full details as to what is included is below in the shortlog.

Please pull from:
	master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-core-2.6.git/

All of these patches have been in the linux-next and mm trees.

The patches will be sent as a follow-on to this message to lkml for
people to see.

thanks,

greg k-h

Subject: [PATCH 06/28] Driver core: Drop __must_check from bus_for_each_drv()
Date: Thursday, August 5, 2010 - 3:23 pm

From: Jean Delvare <khali@linux-fr.org>

There is little rationale for marking bus_for_each_drv() __must_check.
It is more of an iteration helper than a real function. You don't know
in advance which callback it will be used on, so you have no clue how
important it can be to check the returned value. In practice, this
helper function can be used for best-effort tasks.

As a matter of fact, bus_for_each_dev() is not marked __must_check.
So remove it from bus_for_each_drv() as well. This is the same that
was done back in October 2006 by Russell King for
device_for_each_child(), for exactly the same reasons.

Date: Thursday, August 5, 2010 - 3:24 pm

From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

Platform devices should only be called by init code, so it should be
possible to move creation helpers to .init.text -- at least if modules
are disabled.

Subject: [PATCH 20/28] Driver core: Add BUS_NOTIFY_BIND_DRIVER
Date: Thursday, August 5, 2010 - 3:24 pm

From: Magnus Damm <damm@opensource.se>

Add BUS_NOTIFY_BIND_DRIVER as a bus notifier event.

For driver binding/unbinding we with this in
place have the following bus notifier events:
 - BUS_NOTIFY_BIND_DRIVER - before ->probe()
 - BUS_NOTIFY_BOUND_DRIVER - after ->probe()
 - BUS_NOTIFY_UNBIND_DRIVER - before ->remove()
 - BUS_NOTIFY_UNBOUND_DRIVER - after ->remove()

The event BUS_NOTIFY_BIND_DRIVER allows bus code
to be notified that ->probe() is about to be called.

Useful for bus code that needs to setup hardware before
the driver gets to run. With this in place platform
drivers can be loaded and unloaded as modules and the
new BIND event allows bus code to control for instance
device clocks that must be enabled before the driver
can be executed.

Without this patch there is no way for the bus code to
get notified that a modular driver is about to be probed.

Subject: [PATCH 21/28] cgroupfs: create /sys/fs/cgroup to mount cgroupfs on
Date: Thursday, August 5, 2010 - 3:24 pm

From: Greg KH <gregkh@suse.de>

We really shouldn't be asking userspace to create new root filesystems.
So follow along with all of the other in-kernel filesystems, and provide
a mount point in sysfs.

For cgroupfs, this should be in /sys/fs/cgroup/  This change provides
that mount point when the cgroup filesystem is registered in the kernel.

Subject: [PATCH 18/28] debugfs: no longer needs to depend on SYSFS
Date: Thursday, August 5, 2010 - 3:24 pm

From: Randy Dunlap <randy.dunlap@oracle.com>

debugfs no longer uses 'kernel_subsys' (which is gone), and other
kernel/ksysfs.c code is always built, so DEBUG_FS does not need
to depend on SYSFS.

Fixes this kconfig warning:

warning: (TREE_RCU_TRACE || AMD_IOMMU_STATS && AMD_IOMMU || MTD_UBI_DEBUG && MTD && SYSFS && MTD_UBI || UBIFS_FS_DEBUG && MISC_FILESYSTEMS && UBIFS_FS || DEBUG_KMEMLEAK && DEBUG_KERNEL && EXPERIMENTAL && !MEMORY_HOTPLUG && (X86 || ARM || PPC || S390 || SPARC64 || SUPERH || MICROBLAZE) && SYSFS || TRACING || X86_PTDUMP && DEBUG_KERNEL || BLK_DEV_IO_TRACE && TRACING_SUPPORT && FTRACE && SYSFS && BLOCK) selects DEBUG_FS which has unmet direct dependencies (SYSFS)

Date: Thursday, August 5, 2010 - 3:24 pm

From: Magnus Damm <damm@opensource.se>

Update the in-kernel hotplug example script to work
properly with recent kernels. Without this fix the
script may load the firmware twice - both at "add"
and "remove" time.

The second load only triggers in the case when multiple
firmware images are used. A good example is the b43
driver which does not work properly without this fix.

Date: Thursday, August 5, 2010 - 3:23 pm

From: Ian Abbott <abbotti@mev.co.uk>

The kernel/hotplug sysctl variable (/proc/sys/kernel/hotplug file) was
made conditional on CONFIG_NET by commit
f743ca5e10f4145e0b3e6d11b9b46171e16af7ce (applied in 2.6.18) to fix
problems with undefined references in 2.6.16 when CONFIG_HOTPLUG=y &&
!CONFIG_NET, but this restriction is no longer needed.

This patch makes the kernel/hotplug sysctl variable depend only on
CONFIG_HOTPLUG.
