Subject: Re: [net-next PATCH V2 1/9] net: frag evictor, avoid killing warm frag queues
Date: Fri, 30 Nov 2012 15:47:51 -0800 [thread overview]
Message-ID: <20121130154751.06f7d3f7@nehalam.linuxnetplumber.net> (raw)
In-Reply-To: <1354317815.11754.498.camel@localhost>
My $.02 is that this would be a good place to introduce lock-free auto
resizing hash lists that are in the userspace RCU library.
It would be a non-trivial effort to put this in the kernel, but
it would let the table grow transparently.
