Re: Document about page and buffer cache.

["Sushil Patil" <sushilpa@xxxxxxxxx>]

Yeh I think we do have such unified approach now.The following document 
provides some initial pointers on where page & buffer caches were used
and how they can be _unified_ to avoid double copying.

To the best I know, both actually reside in page cache. in <=2.2.x,
they are separated and this leads to synchronization headache.


Buffer cache handles things like icache, dcache etc while page cache
handle page based reading like read()/write() of block devices.
