Re: [PATCH 2/2] block: don't silently ignore metadata for sync read/write

Christoph,

The block fops don't try to handle metadata for synchronous requests,
probably because the completion handler looks at dio->iocb which is
not valid for synchronous requests.

But silently ignoring metadata (or warning in case of
__blkdev_direct_IO_simple) is a really bad idea as that can cause
silent data corruption if a user ever shows up.

Looks fine.
