Subject: [IPV4] ROUTE: Collect proc-related functions together
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=78c686e9faff05f1194e892d5b1273ce24021ff6;p=linux-beck.git

[IPV4] ROUTE: Collect proc-related functions together

The net/ipv4/route.c file declares some entries for proc
to dump some routing info. The reading functions are
scattered over this file - collect them together.

Besides, remove a useless IP_RT_ACCT_CPU macro.
