The commit c0842fbc1b18 ("random32: move the pseudo-random 32-bit definitions to prandom.h") introduced a new header for the pseudo random functions from (previously) linux/random.h. One future goal of the prandom.h change is to make code to switch just the new header file and to avoid the implicit include. This would allow the removal of the implicit include from random.h
