[lustre-devel] [PATCH 08/24] lustre: lnet: rename lnet_add/del_peer_ni_to/from_peer()

[NeilBrown]

From: Olaf Weber <olaf at sgi.com>

Rename lnet_add_peer_ni_to_peer() to lnet_add_peer_ni(), and
lnet_del_peer_ni_from_peer() to lnet_del_peer_ni().  This brings
the function names closer to the ioctls they implement:
IOCTL_LIBCFS_ADD_PEER_NI and IOCTL_LIBCFS_DEL_PEER_NI. These
names are also a more accturate description their effect: adding
or deleting an lnet_peer_ni to LNet.
