[PATCH v3 0/2] random: PREEMPT_RT fixes
From: Jason A. Donenfeld
Date: Mon Feb 07 2022 - 10:44:41 EST
Here are the two patches we've been looking at thus far in separate
threads, now brought together as one patchset. This doesn't fix _all_ of
the PREEMPT_RT issues, but it does very much move in the right direction
of having less locking in places where that matters.
