commit 38c8a9a520 upstream.
Move CIFS/SMB3 related client and server files (cifs.ko and ksmbd.ko
and helper modules) to new fs/smb subdirectory:
fs/cifs --> fs/smb/client
fs/ksmbd --> fs/smb/server
fs/smbfs_common --> fs/smb/common

[ added to stable trees to handle the directory change to handle the
future stable patches due to the constant churn in this filesystem at
the moment - gregkh ]
