The previous patch adding the ability to nest struct class_device changed the paramaters to the call class_device_create(). This patch fixes up all in-kernel users of the function. Signed-off-by: -
Greg Kroah-Hartman authored
This patch allows struct class_device to be nested, so that another struct class_device can be the parent of a new one, instead of only having the struct class be the parent. This will allow us to (hopefully) fix up the input and video class subsystem mess. But please people, don't go crazy and start making huge trees of class devices, you should only need 2 levels deep to get everything to work (remember to use a class_interface to get notification of a new class device being added to the system.) Oh, this also allows us to have the possibility of potentially, someday, moving /sys/block into /sys/class. The main hindrance is that pesky /dev numberspace issue... Signed-off-by: -

A "coldplug + udevstart" can be simple like this: for i in /sys/block/*/*/uevent; do echo 1 > $i; done for i in /sys/class/*/*/uevent; do echo 1 > $i; done for i in /sys/bus/*/devices/*/uevent; do echo 1 > $i; done Signed-off-by:

Driver core: pass interface to class intreface methods Pass interface as argument to add() and remove() class interface methods. This way a subsystem can implement generic add/remove handlers and then call interface-specific ones. Signed-off-by:

I2O: cleanup - remove i2o_device_class I2O devices reside on their own bus so there should be no reason to also have i2c_device class that mirros i2o bus. Signed-off-by:

I2O: remove i2o_device_class_interface misuse The intent of class interfaces was to provide different 'views' at the same object, not just run some code every time a new class device is registered. Kill interface structure, make class core register default attributes and set up sysfs links right when registering class devices. Signed-off-by:

This patch teaches "usb_device" about the new driver model wakeup support: - It updates device wakeup capabilities when entering a configuration with the WAKEUP attribute; - During suspend processing it consults the policy bit to see whether it should enable wakeup for that device. (This resolves a FIXME to not assume the answer is always "yes"; some devices lie about supporting remote wakeup.) Support for root hubs and the HCDs is separate (and more complex). Signed-off-by:

This is a refresh of an earlier patch to add "wakeup" support to the PM core model. This provides per-device bus-neutral control of the use of wakeup events. * "struct device_pm_info" has two bits that are initialized as part of setting up the enclosing struct device: - "can_wakeup", reflecting hardware capabilities - "may_wakeup", the policy setting (when CONFIG_PM) * There's a writeable sysfs "wakeup" file, with one of two values: - "enabled", when the policy is to allow wakeup - "disabled", when the policy is not to allow it - "" if the device can't currently issue wakeups By default, wakeup is enabled on all devices that support it. If its driver doesn't support it ... treat it as a bug. :) Signed-off-by: -

I was recently given an old Travan tape drive and asked to do something useful with it. The ide-scsi + st (+serverworks ide controller) combo results in a hard lockup of the machine which I have not had the energy to debug, so I turned to ide-tape (which seems to work). The system in question debian stable, using udev to manage /dev. The following patch to ide-tape.c allows udev to create the cdev nodes for my drive.

This bug is responsible for causing the infamous "Treason uncloaked" messages that's been popping up everywhere since the printk was added. It has usually been blamed on foreign operating systems. However, some of those reports implicate Linux as both systems are running Linux or the TCP connection is going across the loopback interface. In fact, there really is a bug in the Linux TCP header prediction code that's been there since at least 2.1.8. This bug was tracked down with help from Dale Blount. The effect of this bug ranges from harmless "Treason uncloaked" messages to hung/aborted TCP connections. The details of the bug and fix is as follows. When snd_wnd is updated, we only update pred_flags if tcp_fast_path_check succeeds. When it fails (for example, when our rcvbuf is used up), we will leave pred_flags with an out-of-date snd_wnd value. When the out-of-date pred_flags happens to match the next incoming packet we will again hit the fast path and use the current snd_wnd which will be wrong. In the case of the treason messages, it just happens that the snd_wnd cached in pred_flags is zero while tp->snd_wnd is non-zero. Therefore when a zero-window packet comes in we incorrectly conclude that the window is non-zero. In fact if the peer continues to send us zero-window pure ACKs we will continue making the same mistake. It's only when the peer transmits a zero-window packet with data attached that we get a chance to snap out of it. This is what triggers the treason message at the next retransmit timeout.
