[PATCH 2/6] s390: simplify one-level syctl registration for s390dbf_table

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is no need to declare an extra tables to just create directory,
this can be easily be done with a prefix path with register_sysctl().

Simplify this registration.
