static long get_nr_to_scan(struct lruvec *lruvec, struct scan_control *sc, bool can_swap)
figure out how many pages to scan.
-
static void prepare_scan_control(pg_data_t *pgdat, struct scan_control *sc) {
sets up the struct scan_control. Most of the value come from elsewhere but this function seems to bring it all together.

Cuando sabe bastante de un tema, el aprendiz se convierte en experto. El experto ha practicado tantas veces que normaliza su conocimiento. Sus capacidades se han vuelto inconscientes. Sobre lo que desconoce, en cambio, es muy consciente, lo que le lleva a infravalorar sus capacidades. El nombre chic: el síndrome del impostor.
El síndrome del impostor sale cuando el experto, que ha normalizado lo que sabe, infravalora sus capacidades.
