NETROM: Fix use of static buffer 2009-08-18T01:05:32+00:00 Ralf Baechle ralf@linux-mips.org 2009-08-18T01:05:32+00:00 c6ba973b8fa97422aab4204f7d79f1d413cde925 The static variable used by nr_call_to_digi might result in corruption if multiple threads are trying to usee a node or neighbour via ioctl. Fixed by having the caller pass a structure in. This is safe because nr_add_node rsp. nr_add_neigh will allocate a permanent structure, if needed.
