Possible case of Race in kobject_get_path()

[Mukesh Ojha <quic_mojha@xxxxxxxxxxx>]

Hi All,

We are facing one issue where one driver (p1) is trying to register its 
device from driver probe
and from another path (p2) dev_set_name(new name) done from driver probe 
of the added device whose
new name length can be more than earlier done in (p1 path) which could 
result in redzone overwritten issue.

Can we get your suggestion here ? is this case of a race here ?

            p1                                                   p2

 device_register()
    kobject_get_path()
            =>  get_kobj_path_length
            (length is calculated from this path)

                                                 dev_set_name()

            => fill_kobj_path
              (path is copied here)


Thanks,
