Hi all,
a patch [1] was added some time ago to send upcall notifications from the locks xlator to the current owner of a granted lock when another client tries to acquire the same lock (inodelk or entrylk). This makes it possible to use eager-locking on the client side, which improves performance significantly, while also keeping good performance when multiple clients are accessing the same files (the current owner of the lock receives the notification and releases it as soon as possible, allowing the other client to acquire it and proceed very soon).
Currently both AFR and EC are ready to handle these contention notifications and both use eager-locking. However the upcall contention notification is disabled by default.
I think we should enabled it by default. Does anyone see any possible issue if we do that ?
Regards,
Xavi
