That sounds undesirable. Are you sure that We just need to fix f2fs to support direct I/O on zone devices. There is not good reason not to support it, in fact the way how zoned devices requires appends with the Zone Append semantics makes direct I/O way safer than how f2fs does direct I/O currently on non-zoned devices. Until then just supporting direct I/O reads on zoned devices for f2fs seems like a really bad choice given that it will lead to nasty cache incoherency.
