Description

mmap currently does not support updates on virtual files.
most of the code should be there... maybe we need to implement some optimization in order to save just the required chunks of the file.
We need to define a consistent semantics for processes running inside vuos and processes running outside viewos mmap'ing the same file.

Research direction

Start by locating the existing mmap implementation and the code handling virtual files. Read how updates and file chunks are currently managed, then clarify consistent semantics for mmap calls from processes inside and outside viewos. Done means virtual-file updates work and the interaction between both process contexts is defined and implemented.
