What is this 'kernel_pread_opt' foolishness? Why not just pass in
~0UL as max_size if you want the entire file?
That is not how existing kernel_read_file api works - max_size is specified.
I guess not everyone has unlimited memory to read a file on any size.

extern? really? i'm shocked gcc doesn't vomit on that.
A typo. thanks. You'll have to ask the compiler gods about your shock.
