From 42954c374534f37dd25a4096b52d28e46dc1f8ba Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Tue, 6 Feb 2024 15:08:19 +0100 Subject: quota: Properly annotate i_dquot arrays with __rcu [ Upstream commit ccb49011bb2ebfd66164dbf68c5bff48917bb5ef ] Dquots pointed to from i_dquot arrays in inodes are protected by dquot_srcu. Annotate them as such and change .get_dquots callback to return properly annotated pointer to make sparse happy.
