Yep, but regretfully it has "most but not all" of it (according to the
spec file comments):
# improve interactive "feel" by reducing latency
# (most but not all of Andrew Morton's low latency patch)
#
%patch740 -p1
Not long ago I tried kernel 2.4.18-0.22 from Rawhide and "most" was not
enough for low latency audio work, at least in my limited tests (I was
testing it to see if I could just switch to the "standard" redhat kernel
instead of mantaining my own kernel rpms). I did not check to see what was
omitted but it was enough to create alsa dropouts while using jack and
ardour (as compared to a plain 2.4.18-pre7 plus the full glorious low
latency patch :-)
But I have not tried 7.3 or its kernel yet... maybe they included more of
the low latency patch than in the one I tried.
