No. Linus is not a God, Linus is fallible, regularly makes mistakes and
frequently opens his mouth and says stupid things when he is far too busy.

I agree with the issues about networking wanting lightweight objects, Im
unconvinced however the existing setup for networking is sanely applicable
for real world applications in other spaces.
Take video capture. I want to stream 60Mbytes/second in multi-megabyte
chunks between my capture cards and a high end raid array. The array wants
1Mbyte or large blocks per I/O to reach 60Mbytes/second performance.
This btw isnt benchmark crap like most of the zero copy networking, this is
a real world application..
The current buffer head stuff is already heavier than the kio stuff. The
networking stuff isnt oriented to that kind of I/O and would end up
needing to do tons of extra processing.

I remain to be convinced by that. However you do get 64bytes/cacheline on
a real processor nowdays so if you touch any of that 64byte block you are
practically zero cost to fill the rest.
