Ben Nizette, the author of this driver, told me in a private mail that this project has been cancelled. He suggested to remove the driver for now, and will come back with a new version should the hardware really exist. This patch completely removes the driver. Signed-off-by:

Two trivial fixes for the Userspace IO Kconfig file: 1) uio_sercos3 is a PCI driver, so let it depend on PCI. 2) "default n" under UIO_PCI_GENERIC is luxury since it is already the default. Acked-by:

This patch adds a Userspace IO driver for netX-based fieldbus cards by Hilscher (see http://www.hilscher.com). ATM, cifX and comX cards are supported. The userspace part for this driver is provided by Hilscher and should come with the card. The driver is in use for several months now and has been tested by people at Hilscher and Linutronix.

A pointer to cfag12864bfb_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver. Signed-off-by:

Constify struct sysfs_ops. This is part of the ops structure constification effort started by Arjan van de Ven et al. Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by:

One of the roles which -mm fulfilled some time ago (to offer an integration testing ground) has been taken over by -next. This is still news to Documentation/HOWTO, so mention it there. Also add a word on how patchwork is used to track patches as they make their way into subsystem trees. Remove some arbitrary links to subsystem repositories; they can all be found in the MAINTAINERS database. Acked-by:

When sysfs_readdir stops short we now cache the next sysfs_dirent to return to user space in filp->private_data. There is no impact on the rest of sysfs by doing this and in the common case it allows us to pick up exactly where we left off with no seeking. Additionally I drop and regrab the sysfs_mutex around filldir to avoid a page fault abritrarily increasing the hold time on the sysfs_mutex. v2: Returned to using INT_MAX as the EOF condition. seekdir is ambiguous unless all directory entries have a unique f_pos value.

Before unlinking the inode, reset the current permissions of possible references like hardlinks, so granted permissions can not be retained across the device lifetime by creating hardlinks, in the unusual case that there is a user-writable directory on the same filesystem. Signed-off-by:

Several drivers just export a static string as class attributes. Use the new extensible attribute support to define a simple CLASS_ATTR_STRING() macro for this. This will allow to remove code from drivers in followon patches. Signed-off-by:

Passing the attribute to the low level IO functions allows all kinds of cleanups, by sharing low level IO code without requiring an own function for every piece of data. Also drivers can extend the attributes with own data fields and use that in the low level function. This makes the class attributes the same as sysdev_class attributes and plain attributes. This will allow further cleanups in drivers. Full tree sweep converting all users. Signed-off-by:

Andi Kleen authored
Add a attribute array that is automatically registered and unregistered to struct sysdev_class. This is similar to what struct class has. A lot of drivers add list of attributes, so it's better to do this easily in the common sysdev layer. This adds a new field to struct sysdev_class. I audited the whole tree and there are no dynamically allocated sysdev classes, so this is fully compatible. Signed-off-by:

Passing the attribute to the low level IO functions allows all kinds of cleanups, by sharing low level IO code without requiring an own function for every piece of data. Also drivers can extend the attributes with own data fields and use that in the low level function. Similar to sysdev_attributes and normal attributes. This is a tree-wide sweep, converting everything in one go. No functional changes in this patch other than passing the new argument everywhere. Tested on x86, the non x86 parts are uncompiled.
