Ok so I have an application where I need to reread a file I have just written to ensure that it went to disk correctly.. Other than reading a few GB of data, is there a way to flush out the cache copy of a file I've written? possibilities include: a file flag saying "don't keep a copy after it's written to disk"? a syscall discard_cached_blocks(fd); ? any other suggestions? julian (BTW this would be for 4.x initially)
