I wonder whether there is any way to test such unusual configurations?
Only randconfig or are there any (partly-)automated tools for it?
[PATCH] net: ping: fix build failure
If CONFIG_PROC_SYSCTL=n the building process fails:
ping.c:(.text+0x52af3): undefined reference to `inet_get_ping_group_range_net'
Moved inet_get_ping_group_range_net() to ping.c.
