Merge tag 'random_for_linus_stable' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random
Pull /dev/random fixes from Ted Ts'o:
"Fix some bugs in the /dev/random driver which causes getrandom(2) to
unblock earlier than designed.
Thanks to Jann Horn from Google's Project Zero for pointing this out
to me"
* tag 'random_for_linus_stable' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random:
random: add new ioctl RNDRESEEDCRNG
random: crng_reseed() should lock the crng instance that it is modifying
random: set up the NUMA crng instances after the CRNG is fully initialized
random: use a different mixing algorithm for add_device_randomness()
random: fix crng_ready() test
