Subject: [PATCH v4 0/2] cpuhp enhancements
Date: Tue, 15 Feb 2022 22:22:53 +0100	[thread overview]
Message-ID: <20220215212255.273253-1-Jason@zx2c4.com> (raw)

This series combines the two uses thus far identified for cpuhp in
random.c. v3 uses prepare instead of teardown. v4 guards the added
function with CONFIG_SMP, since it's not used on !CONFIG_SMP.

Jason A. Donenfeld (2):
  random: set fast pool count to zero in cpuhp prepare
  random: invalidate crngs and batches in cpuhp prepare
