First, thank you for looking in to this. Second, please run
"scripts/checkpatch.pl" against each as there's inconsistent spacing
used here and that makes review harder (and needs to be fixed before
applying). Finally, for each commit please elaborate on the problem
being fixed (for example "if ... is corrupted then ... could
oveverflow"). Thanks!
