Replace strlen(fn) with strnlen(fn, NAME_MAX + 1) when validating the final path component in __proc_create(). This preserves the existing name limit while bounding the length scan to one byte past the maximum name length. Handle empty names separately, and treat names longer than NAME_MAX as too long.
