There's a chunky comment near the beginning of filemap_nopage() that after a test and then following the source seems to me to be untrue: /* * Semantics for shared and private memory areas are different * past the end of the file. A shared mapping past the last page * of the file is an error and results in a SIGBUS, while a * private mapping just maps in a zero page. */ I tried to read past on a MAP_PRIVATE and got a sigbus and the source seems to suggest no differentiation from MAP_SHARED in this respect. What are the `correct' semantics?
