statfs() gives ESTALE error
Hi,
An NFS client executes a statfs("file", &buff) call.
"file" exists / existed, the client has read / written it,
but it has already closed it.
user_path(pathname, &path) looks up "file" successfully in the
directory-cache and restarts the aging timer of the directory-entry.
Even if "file" has already been removed from the server, because the
lookupcache=positive option I use, keeps the entries valid for a while.
nfs_statfs() returns ESTALE if "file" has already been removed from the
server.
If the user application repeats the statfs("file", &buff) call, we
are stuck: "file" remains young forever in the directory-cache.
