What it is

In the Linux kernel, the following vulnerability has been resolved:

cifs: some missing initializations on replay

In several places in the code, we have a label to signify

the start of the code where a request can be replayed if

necessary. However, some of these places were missing the

necessary reinitializations of certain local variables

before replay.

This change makes sure that these variables get initialized

after the label.
