[PATCH] Fix the fdtable freeing in the case of vmalloced fdset/arrays
Noted by David Miller:
"The bug is that free_fd_array() takes a "num" argument, but when
calling it from __free_fdtable() we're instead passing in the size in
bytes (ie. "num * sizeof(struct file *)")."
Yes it is a bug. I think I messed it up while merging newer
changes with an older version where I was using size in bytes
to optimize.
