Hello,
I had seen that patch in Ubuntu but had disregarded it. I am not
perfectly sure about ionice syntax, but I think that
IONICE_CLASS 3 idle seems to be perfect for locate.
ionice(1) says
"-n The scheduling class data. This defines the class data, if the
class accepts an argument. For real time and best-effort, 0-7 is valid
data."
This implies that setting -n for -c3 is a error. At the time being
ionice simply seems to ignore -n if -c3 is set, though.
Why are you defaulting to IONICE_CLASS 2 instead of 3? How is this
better? Is there some policy I am not aware of?
thanks, cu andreas
