From c1af01da79ef67868bc95a113a8613cf26d9c931 Mon Sep 17 00:00:00 2001 From: James Simmons Date: Wed, 21 Oct 2015 21:52:44 -0400 Subject: [PATCH] staging: lustre: move cfs_ip_addr_* function from kernel libcfs to LNet Both of cfs_ip_addr_parse and cfs_ip_addr_match which are located in libcfs kernel module are used only for LNet so move this into the nidstring handling code where it belongs. Also create user land versions of these functions in the libcfs user land library.
