Subject: cifs: make sure we ignore the credentials= and cred= options
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=a557b97616c49d81e09c8439831d4c4f13ef4050;p=deliverable%2Flinux.git

cifs: make sure we ignore the credentials= and cred= options

Older mount.cifs programs passed this on to the kernel after parsing
the file. Make sure the kernel ignores that option.

Should fix:
