Jens Axboe 2d1b3bbc3d ovl: disable IOCB_DIO_CALLER_COMP ... overlayfs copies the kiocb flags when it sets up a new kiocb to handle a write, but it doesn't properly support dealing with the deferred caller completions of the kiocb. This means it doesn't get the final write completion value, and hence will complete the write with '0' as the result. We could support the caller completions in overlayfs, but for now let's just disable them in the generated write kiocb.
