[PATCH 6/6] sysctl: stop exporting register_sysctl_table

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

 



We make register_sysctl_table static because the only function calling
it is in fs/proc/proc_sysctl.c (__register_sysctl_base). We remove it
from the sysctl.h header and modify the documentation in both the header
and proc_sysctl.c files to mention "register_sysctl" instead of
"register_sysctl_table".
