| |
Hi All,
In the development of RPA PCI Hot Plug Controller driver, I have found it is needed to create some kernel objects which have more than 20 (KOBJECT_NAME_SIZE) charaters in their name strings. At a later time the names will be used for creating some symlinks. The attached patch adds unlimited name lengths support to sysfs symlink.c.
Comments are welcome.
Linda
