Last year, fdatasync() was changed to allow syncing files opened read-only, because that ceased to be prohibited by POSIX and something apparently depended on it.
However, fsync_range() was not also so changed. Should it have been? It's now inconsistent with fsync and fdatasync and it seems like it's meant to be a strict superset of them. -- David A. Holland dholl...@netbsd.org
