From: Greg KH on 22 Apr 2010 16:00 2.6.32-stable review patch. If anyone has any objections, please let us know. ------------------ From: Steve French <sfrench(a)us.ibm.com> commit a24e2d7d8f512340991ef0a59cb5d08d491b8e98 upstream. By doing this we always overwrite nbytes value that is being passed on to CIFSSMBWrite() and need not rely on the callers to initialize. CIFSSMBWrite2 is doing this already.
