SubjectRe: read() called twice for /proc files

This results in the actual read taking twice as long. Perhaps I am missing

EOF isn't known until you return the zero. You can watch the loff_t
arg to the read operation to see if it is at the end, and if so just
avoid retouching the device or whatever and go straight to returning

Franks a lot,
