MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 581 Lines: 17 Hi, NFS/VFS gurus nfs_access_cache_shrinker() calls igrab() without serialized with umount process, looks that might cause the "busy inode" after umount, doesn't it? I think we need to serialize the generic_shutdown_super() and nfs_access_cache_shrinker() just like the dcache/icache shrinker, am I understanding right?
