Subject: cifs: fix protocol definition for READ_RSP
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=2ab2593f4b8953ff951f5531e695e487dfe0b51f;p=deliverable%2Flinux.git

cifs: fix protocol definition for READ_RSP

There is no pad, and it simplifies the code to remove the "Data" field.

None of the existing code relies on these fields, or on the READ_RSP
being a particular length.
