Should it be static? drivers/staging/lustre/lustre/libcfs/nidstrings.c:307:18: warning: symbol 'libcfs_name2netstrfns' was not declared. Should it be static? Some functions had static forward declarations followed by non-static implementations. Those forward declarations are removed and the implementations are declared static and moved into a location that doesn't require forward declarations.
