With your patch and without it, please.
Yes I will do, thanks.
PS: getting rid of socket dentries is a bad idea with the capital "Fuck, No".
For those who want to see where does that path lead and are attracted to
trainwrecks in general I can recommend *BSD socket handling. They have
paid quite painfully for lack of proper vnodes. It's simply not worth
the resulting trouble.
I have one server with one million sockets, wasting 210 MB of ram for dentries
that are only used when some guy does some /proc/$pid/fd work
Socket hot path already dont use anymore dentries, thanks to file->private_data
