../fs/d_path.c:52: warning: Excess function parameter 'buffer' description in 'prepend_name'
../fs/d_path.c:52: warning: Excess function parameter 'buflen' description in 'prepend_name'
../fs/d_path.c:127: warning: Excess function parameter 'buffer' description in 'prepend_path'
../fs/d_path.c:127: warning: Excess function parameter 'buflen' description in 'prepend_path'
