Hello,
I would like to obtain more information about the internals (or
inexistence thereof) of raw devices. How is synchronization with the
buffer cache guaranteed?
In particular, say that I want to insert an intermediate (e.g. encryption)
layer in between the buffer cache and the device driver; will raw I/O
bypass this (I presume it will). Is there any possibility to prevent this
(say that my hard disk is encrypted and I want to decrypt before any
information is accessed)?
Thank for any suggestions,
Erik De Win
