Subject: [PATCH 0/4] Fix queued spinlocks and a bit more
Date: Fri, 23 Apr 2021 13:11:04 +1000 [thread overview]
Message-ID: <20210423031108.1046067-1-npiggin@gmail.com> (raw)
Patch 1 is the important fix. 2 might fix something, although I haven't
provoked a crash yet.
Patch 3 is a small cleanup, and patch 4 I think is the right thing to do
but these could wait for later.
Thanks,
Nick
