This is a small cleanup patch that makes the code just a little bit cleaner. Signed-off-by:

This patch modifies the users of sysfs_mount to use sysfs_root instead (which is what they are looking for). It then makes sysfs_mount static to keep people from using it by accident. The net result is slightly faster and cleaner code. Signed-off-by:

Since sysfs no longer stores fs directory information in the dcache on a permanent basis kill_litter_super it is inappropriate and actively wrong. It will decrement the count on all dentries left in the dcache before trying to free them. At the moment this is not biting us only because we never unmount sysfs. Signed-off-by:

Now that sysfs_get_inode is dropping the inode lock we no longer have a need from sysfs_instantiate. Signed-off-by:

While platform_device.id is a u32, platform_device_add() handles "-1" as a special id value. This has potential for confusion and bugs. Making it an int instead should prevent problems from happening in the future. Signed-off-by:

No one uses sysdev_drivers. Because no one calls sysdev_driver_register with NULL class. And it is difficult to imagine that someone want to implement a global sysdev driver which is called with all sys_device on any kind of sysdev_class. So this patch removes global sysdev_drivers list and update comments for this change. Signed-off-by:

following patch fixes the i2c name collision with i2c-dev. http://mcentral.de/wiki/index.php/Bugtracker#i2c_core_problem This issue has been experienced with em28xx and saa7133 based devices. I discussed that problem with Jean Delvare a while ago and he proposed to add a prefix to the class name. Signed-off-by:

We can use sysfs attributes with an extra parameter for dmi id attributes. This makes it possible to use the same callback function for all attributes, reducing the binary size significantly (-18% on x86_64.) Signed-off-by:

With the previous sysfs_add_one() update, there is only one user of the return value of sysfs_addrm_finish() and the user can switch to testing @sd easily. Make sysfs_addrm_finish() return void for cleaner semantics as suggested by Satyam Sharma. This patch doesn't introduce any noticeable behavior change. Signed-off-by:

Make sysfs_add_one() check for duplicate entry and return -EEXIST if such entry exists. This simplifies node addition code a bit. This patch doesn't introduce any noticeable behavior change. Signed-off-by:

When adding or removing a sysfs_dirent, the user used to be required to call link/unlink separately. It was for two reasons - code looked like that before sysfs_addrm_cxt conversion and to avoid looping through parent_sd->children list twice during removal. Performance optimization during removal just isn't worth it. Make sysfs_add/remove_one() call sysfs_link/unlink_sibing() implicitly. This makes code simpler albeit slightly less efficient. This change doesn't introduce any noticeable behavior change. Signed-off-by:

With the shadow directories gone, sysfs_rename_dir() can be simplified. * parent doesn't need to be grabbed separately. Just access old_dentry->d_parent. * parent sd can never change. Remove code to move under the new parent. * Massage comments a bit. Signed-off-by:

* remove space between * and symbol name in variable declaration. * kill unnecessary new line. * kill 'found' and test 'sd' instead. Signed-off-by:

While shadow directories appear to be a good idea, the current scheme of controlling their creation and destruction outside of sysfs appears to be a locking and maintenance nightmare in the face of sysfs directories dynamically coming and going. Which can now occur for directories containing network devices when CONFIG_SYSFS_DEPRECATED is not set. This patch removes everything from the initial shadow directory support that allowed the shadow directory creation to be controlled at a higher level. So except for a few bits of sysfs_rename_dir everything from commit b592fcfe is now gone. Signed-off-by:

Due to historical reasons, struct kobject contained a static array for the name, and a dynamic pointer in case the name got bigger than the array. That's just dumb, as people didn't always know which variable to reference, even with the accessor for the kobject name. This patch removes the static array, potentially saving a lot of memory as the majority of kobjects do not have a very long name. Thanks to Kay for the idea to do this.

A kset should not have its name set directly, so dynamically set the name at runtime. This is needed to remove the static array in the kobject structure which will be changed in a future patch. Signed-off-by: -

A number of different drivers incorrect access the kobject name field directly. This is not correct as the name might not be in the array. Use the proper accessor function instead.

The kernel creates a process for every event that is send, even when there is no binary it could execute. We are needlessly creating around 200-300 failing processes during early bootup, until we have the chance to disable it from userspace. This change allows us to disable /sbin/hotplug entirely, if you want to, by setting UEVENT_HELPER_PATH="" in the kernel config. Signed-off-by:

This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.
