smb: move client and server files to common directory fs/smb
commit 38c8a9a52082579090e34c033d439ed2cd1a462d 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 Suggested-by: Linus Torvalds <torvalds@linux-foundation.org> Acked-by: Namjae Jeon <linkinjeon@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com> [ 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 ] Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
