Hi, for POSIX_FADV_DONTNEED, syncing with fsync(2) or fdatasync(2) is recommended in the man page of posix_fadvise(2). However, for this task sync_file_range(2) is probably best suited, as it is fast and has the same granularity as posix_fadvise(2). akpm also used sync_file_range(2) for his user space helpers: http://userweb.kernel.org/~akpm/pagecache-management/pagecache-management/pagecache-management.c So I suggest to add sync_file_range(2) to the list of mentioned sync functions.
