094eca3719 NFSv4: Fix up RCU annotations for struct nfs_netns_client 
The identifier is read as an RCU protected string. Its value may
be changed during the lifetime of the network namespace by writing
a new string into the sysfs pseudofile (at which point, we free the
old string only after a call to synchronize_rcu()).

1f9b0f3afb NFS: Use the correct style for SPDX License Identifier 
This patch corrects the SPDX License Identifier style in
header file related to NFS Client support.
For C header files Documentation/process/license-rules.rst
mandates C-like comments (opposed to C source files where
C++ style should be used).

Changes made by using a script provided by Joe Perches here:
https://lkml.org/lkml/2019/2/7/46.

bf11fbdb20 NFS: Add sysfs support for per-container identifier 
In order to identify containers to the NFS client, we add a per-net
sysfs attribute that udev can fill with the appropriate identifier.
The identifier could be a unique hostname, but in most cases it
will probably be a persisted uuid.
