Without this change I can't set an attribute exactly PAGE_SIZE in length. There is no need for zero termination because the interface uses lengths. From: Jon Smirl <jonsmirl@gmail.com> Signed-off-by: -

o Following patch sets the attributes for newly allocated inodes for sysfs objects. If the object has non-default attributes, inode attributes are set as saved in sysfs_dirent->s_iattr, pointer to struct iattr. Signed-off-by:

o This adds ->i_op->setattr VFS method for sysfs inodes. The changed attribues are saved in the persistent sysfs_dirent structure as a pointer to struct iattr. The struct iattr is allocated only for those sysfs_dirent's for which default attributes are getting changed. Thanks to Jon Smirl for this suggestion. Signed-off-by:

Finally (phew!) this patch demonstrates how to adapt the adm1026 to take advantage of the new callbacks, and the i2c-sysfs.h defined structure/macros. Most of the other sensor/hwmon drivers could be updated in the same way. The odd few exceptions (bmcsensors for example) however might be better off with their own custom attribute structure.

This patch creates a new header with a potential standard i2c sensor attribute type (which simply includes an int representing the sensor number/index) and the associated macros, SENSOR_DEVICE_ATTR to define a static attribute and to_sensor_dev_attr to get a sensor_device_attribute reference from an embedded device_attribute reference.

Based on the discussion about spufs attributes, this is my suggestion for a more generic attribute file support that can be used by both debugfs and spufs. Simple attribute files behave similarly to sequential files from a kernel programmers perspective in that a standard set of file operations is provided and only an open operation needs to be written that registers file specific get() and set() functions. These operations are defined as void foo_set(void *data, u64 val); and u64 foo_get(void *data); where data is the inode->u.generic_ip pointer of the file and the operations just need to make send of that pointer. The infrastructure makes sure this works correctly with concurrent access and partial read calls. A macro named DEFINE_SIMPLE_ATTRIBUTE is provided to further simplify using the attributes. This patch already contains the changes for debugfs to use attributes for its internal file operations. Signed-off-by:

This patch fixes usb_driver_release_interface() to make it avoid calling device_release_driver() recursively, i.e., when invoked from within the disconnect routine for the same device. The patch applies to your "driver" tree. Signed-off-by:

This patch is intended for your "driver" tree. It fixes several subtle races in driver_detach() and device_release_driver() in the driver-model core. The major change is to use klist_remove() rather than klist_del() when taking a device off its driver's list. There's no other way to guarantee that the list pointers will be updated before some other driver binds to the device. For this to work driver_detach() can't use a klist iterator, so the loop over the devices must be written out in full. In addition the patch protects against the possibility that, when a driver and a device are unregistered at the same time, one may be unloaded from memory before the other is finished using it.

The original code looks like this: /* if interface was already added, bind now; else let * the future device_add() bind it, bypassing probe() */ if (!list_empty (&dev->bus_list)) device_bind_driver(dev); IOW, it's checking to see if the device is attached to the bus or not and binding the driver if it is. It's checking the device's bus list, which will only appear empty when the device has been initialized, but not added. It depends way too much on the driver model internals, but it seems to be the only way to do the weird crap they want to do with interfaces. When I converted it to use klists, I accidentally inverted the logic, which led to bad things happening. This patch returns the check to its orginal value.

There's no check to see if the device is already bound to a driver, which could do bad things. The first thing to go wrong is that it will try to match a driver with a device already bound to one. In some cases (it appears with USB with drivers/usb/core/usb.c::usb_match_id()), some drivers will match a device based on the class type, so it would be common (especially for HID devices) to match a device that is already bound. The fun comes when ->probe() is called, it fails, then driver_probe_device() does this: dev->driver = NULL; Later on, that pointer could be be dereferenced without checking and cause hell to break loose. This problem could be nasty. It's very hardware dependent, since some devices could have a different set of matching qualifiers than others. Now, I don't quite see exactly where/how you were getting that crash. You're dereferencing bad memory, but I'm not sure which pointer was bad and where it came from, but it could have come from a couple of different places. The patch below will hopefully fix it all up for you. It's against 2.6.12-rc2-mm1, and does the following: - Move logic to driver_probe_device() and comments uncommon returns: 1 - If device is bound 0 - If device not bound, and no error error - If there was an error. - Move locking to caller of that function, since we want to lock a device for the entire time we're trying to bind it to a driver (to prevent against a driver being loaded at the same time). - Update __device_attach() and __driver_attach() to do that locking. - Check if device is already bound in __driver_attach() - Update the converse device_release_driver() so it locks the device around all of the operations. - Mark driver_probe_device() as static and remove export. It's an internal function, it should stay that way, and there are no other callers. If there is ever a need to export it, we can audit it as necessary. Signed-off-by: -

Thanks for making the changes. However, changes in functions: void pcie_port_device_remove(struct pci_dev *dev) and static int remove_iter(struct device *dev, void *data) are not correct. Please use the patch, which is based on kernel 2.6.12-rc1, below for a fix for these. Signed-off-by: -
