Subject: [PATCH v5 36/45] xfs: dynamically allocate the xfs-qm shrinker
Date: Thu, 24 Aug 2023 11:42:55 +0800 [thread overview]
Message-ID: <20230824034304.37411-37-zhengqi.arch@bytedance.com> (raw)
In-Reply-To: <20230824034304.37411-1-zhengqi.arch@bytedance.com>
In preparation for implementing lockless slab shrink, use new APIs to
dynamically allocate the xfs-qm shrinker, so that it can be freed
asynchronously via RCU. Then it doesn't need to wait for RCU read-side
critical section when releasing the struct xfs_quotainfo.
