Even though the function is generic enough, <anything>sort() inherits connotations from the standard function qsort() that sorts an array. Rename it to llist_mergesort() and describe the external interface in its header file. This incidentally avoids name clashes with mergesort() some platforms declare in, and contaminate user namespace with, their <stdlib.h>.
