Hi All,
Hi,
I can see below warning during boot on few TI boards am437x-idk, am335x-evm, am335x-ice
All of them are non-SMP
I somehow missed the !SMP kernel… What about this:
Subject: [PATCH] RCU: skip the "schedule() in RCU section" warning on UP, too
In "RCU: we need to skip that warning but only on sleeping locks" we
skipped a warning on SMP systems in case we schedule out in a RCU
section while attempt to obtain a sleeping lock. This is also required
on UP systems.
In order to do so, I introduce a tiny version of migrate_disable() +
_enable() which only update the counters which we then can check against
on RT && !SMP.
