[PATCH rcu 20/26] rcu: Rename struct rcu_data .exp_dynticks_snap into .exp_watching_snap

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Valentin Schneider <vschneid@xxxxxxxxxx>

The context_tracking.state RCU_DYNTICKS subvariable has been renamed to
RCU_WATCHING, and the snapshot helpers are now prefix by
"rcu_watching". Reflect that change into the storage variables for these
snapshots.
