+[ cifs_debug.c was moved from fs/cifs to fs/smb/client since
+  38c8a9a52082 ("smb: move client and server files to common directory fs/smb").
+  The cifs_ses_exiting() was introduced to cifs_debug.c since
+  ca545b7f0823 ("smb: client: fix potential UAF in cifs_debug_files_proc_show()")
+  which has been sent to upstream already. ]
