Subject: [PATCH v3 0/2] random: PREEMPT_RT fixes
Date: Mon, 7 Feb 2022 16:39:12 +0100 [thread overview]
Message-ID: <20220207153914.365931-1-Jason@zx2c4.com> (raw)
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.
