Applications use fsync/fdatasync to make sure data is written back to
storage. It is expected that those system calls return error if
writeback has failed (e.g. disk/transport failure, memory failure..)

However if admins run a command such as sync or fsfreeze along side,
fsync/fdatasync may return success even if writeback has failed.
That could lead to data corruption.

This patch is a minimal fix for the problem.
