It is very hard for me that they are VFS lookup bug. If they are really VFS lookup bug, you or Tomas should ask for kernel people to fix them. > That would just be papering over the real problem, a race would still > be there, and the use of stale meta-data for network filesystems (fuse > or non-fuse) would still be there. The network filesystems should have their dentry/inode caches and reuse them within the specified period as their lifetime. After the period expired, the dentry should be revalidated and lookup (and refresh its attribute) if needed. Within the period, the staleness will be allowed since they are remote.
