Brian Behlendorf dfc166d174 Limit sysfs name to KOBJ_NAME_LEN 
It appears that in earlier kernels the maximum name length of a
kobject was KOBJ_NAME_LEN (20) bytes.  This was later extended to
dynamically allocate enough memory if it was over KOBJ_NAME_LEN,
and finally it was always made dynamic.  Unfortunately, util this
last step happened it doesn't look like it always safe to use
names larger than KOBJ_NAME_LEN.  For example, under the RHEL5
2.6.18 kernel if the kobject name length exceeds KOBJ_NAME_LEN
a NULL dereference is tripped.

To avoid this issue the build system has been update to check
to see if KOBJ_NAME_LEN is defined.  If it is we have to assume
the maximum kobject name length is only 20 bytes.  This 20 byte
name must minimally include the following components.
