Revision 75356a8143426a1301bc66c4fb920dcb1bd5e934 authored by Dan Carpenter on 23 January 2013, 20:38:34 UTC, committed by David S. Miller on 28 January 2013, 00:31:03 UTC
We did this for IPv4 in b49d3c1e1c "net: ipmr: limit MRT_TABLE identifiers" but we need to do it for IPv6 as well. On IPv6 the name is "pim6reg" instead of "pimreg" so there is one less digit allowed. The strcpy() is in ip6mr_reg_vif().
