driver core: fix driver_match_device

2009-04-16T23:17:09+00:00

This patch fixes a bug introduced in commit
49b420a13ff95b449947181190b08367348e3e1b.

If a instance of bus_type doesn't have  .match method,
all .probe of drivers in the bus should be called, or else
the .probe have not a chance to be called.

driver core: move knode_bus into private structure

2009-03-24T23:38:25+00:00

Nothing outside of the driver core should ever touch knode_bus, so
move it out of the public eye.

driver core: create a private portion of struct device

2009-03-24T23:38:25+00:00

This is to be used to move things out of struct device that no code
outside of the driver core should ever touch.

driver core: check bus->match without holding device lock

2009-03-24T23:38:24+00:00

This patch moves bus->match out from driver_probe_device and
does not hold device lock to check the match between a device
and a driver.

The idea has been verified by the commit 6cd495860901,
which leads to a faster boot. But the commit 6cd495860901 has
the following drawbacks: 1),only does the quick check in
the path of __driver_attach->driver_probe_device, not in other
paths; 2),for a matched device and driver, check the same match
twice. It is a waste of cpu ,especially for some drivers with long
device id table (eg. usb-storage driver).

This patch adds a helper of driver_match_device to check the match
in all paths, and testes the match only once.

PM: Split up sysdev_[suspend|resume] from device_power_[down|up]

2009-02-22T18:33:44+00:00

Move the sysdev_suspend/resume from the callee to the callers, with
no real change in semantics, so that we can rework the disabling of
interrupts during suspend/hibernation.

This is based on an earlier patch from Linus.

This reverts commit 2831fe6f9cc4e16c103504ee09a47a084297c0f3.

Turns out that device_initialize shouldn't fail silently.
This series needs to be reworked in order to get into proper
