Nope. The git tree hasn't been updated yet, or is this kind of delay
expected (mirroring)?

FYI: The locking bug (deadlock) below was observed on v4.19.257-cip81
and will be fixed by v4.19.259-cip82 as the necessary fix comes from
v4.19.259.

Faulty commit (since v.4.19.238):

242a3e0c75b6 ("SUNRPC: avoid race between mod_timer() and del_timer_sync()")

Fix (since v4.19.259):

bcab4d551a3d ("SUNRPC: use _bh spinlocking on ->transport_lock")

Best regards,
Florian

That would be a bit long for a delay, I guess this is a case of missed
push.

Right, I forgot to push to repository...
I pushed yesterday afternoon (14:00 JST), so it is updated.

I see the updates now.

There's good match of v5.10.145-cip17, v5.10.145-rt74, I'll likely get
advantage of that.

On 4.19 side, last -rt is Aug 13, Linux 4.19.255-rt113. I'd like
matchig -cip release when next 4.19-rt is released.

Thank you and best regards,
