__list_for_each - iterate over a list
"__list_for_each(" "pos" ", " "head" ");"
pos
the &struct list_head to use as a loop cursor.headthe head for your list.
This variant differs from list_for_eachfR
in that it's the simplest possible list iteration code, no prefetching is done. Use this for code that knows the list to be very short (empty or 1 entry) most of the time.
