Linux 2.4 directory notification api in tail -f

[toad]

Will you accept a patch that allows tail -f to use (optionally, but by default
if supported) the linux 2.4 dnotify API rather than polling? We can then
achieve the effect of tail -f --sleep-interval=0 while using minimal CPU.
This isn't written yet, but it's something I'll do (hopefully) if you say yes.
