Hi all,
From the mmap(2) manpage it says:
MAP_PRIVATE Create a private copy-on-write mapping. Stores to the region do not affect the original file. It is unspecified whether changes made to the file after the mmap call are visible in the mapped region.
What is linux behaivour in this area? I am guessing if the page is modified between the call to mmap() and fault-in then the modified copy is seen by the application? But what about modifications after the page is already in page-cache?
Thanks.
