Subject: doesn't nfs_access_cache_shrinker() race with umount?

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?

Thanks
