: [Possible Spam] Re: Linux LPAR - how to drop caching
This has nothing to do with the everything is a file philosophy. It has to do with
the fact that most *ix systems don't have a layer below them to do buffering.
Actually even when you do the overhead of calling down to the driver for every write
something about mmap and fault loading, but it
could be done.

This takes us
This takes us back to the wonderful world of Logical IOCS vs Physical IOCS. In the
Mainframe world there as always been a diference between Logical I/O (the program's
write of 80 bytes) and the Physical I/O (the writing of a 4K data block to a device
by an operating system). In the PC
something about mmap and fault loading, but it
could be done.
