[lustre-devel] [PATCH 03/25] lnet: discard lnet_current_net_count

[James Simmons <jsimmons@infradead.org>]

From: Mr NeilBrown <neilb@suse.de>

The variable lnet_current_net_count is never used.  So remove it.
The function lnet_get_net_count() is only used to update thar
variable, so remove it too.
