SubjectPATCPATCH -- add unlimited name lengths support to sysfs
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
