This matches the approach in upstream commit > d484d621d40f ("ksmbd: add durable scavenger timer"). Thanks for the backport. The 6.12.y version has been queued. For 6.6.y, the diff isn't a straight cherry-pick and the rewritten ksmbd_free_global_file_table() path in particular is a non-trivial stable-only adaptation. Before I queue this for 6.6.y, could you get Acks from the ksmbd maintainers on the 6.6.y diff specifically? In particular: Namjae Jeon Steve French Once one of them has Ack'd the 6.6 adaptation I'll pick it up. -- Thanks, Sasha
