From: Denis V. Lunev <hidden>
Date: 2008-02-19 07:31:15
Subsystem:
bonding driver, networking drivers, networking [general], s390 architecture, s390 network drivers, sctp protocol, the rest · Maintainers:

ip_fib_init is kept enabled. It is already namespace-aware. Signed-off-by: Denis V. Lunev <redacted> --- drivers/net/bonding/bond_main.c | 3 +++ drivers/net/via-velocity.c | 3 +++ drivers/s390/net/qeth_main.c | 3 +++ net/sctp/protocol.c | 3 +++ 4 files changed, 12 insertions(+), 0 deletions(-)
