Hi,

Hi, your patch looks good. what was actually happening was that thhe content of the memory-mapped file wasn't sent for serialization  by the malloc'ed buffer and so the cdbr fails with EINVAL and returned NULL. (probably due to size of buffer). copying to make sure the contents of the of the file are sent to kernel by buffer is the right thing to do. looks fine to be committed and request pullup to 10 and 11 i guess.



A scoffer seeks wisdom in vain, but knowledge is easy for a man of understanding.
