[PATCH 0/2] cifs: fix integer overflow in match_server()

[Roman Smirnov]

If a large number is written to echo_interval during mount,
an integer overflow may occur in match_server():

smb3_fs_context_parse_param()

cifs_smb3_do_mount()
  sget()
    cifs_match_super()
      match_server()

Found by Linux Verification Center (linuxtesting.org) with Svace.
