David Chinner e927af90aa [XFS] Block on unwritten extent conversion during synchronous direct I/O. ... Currently we do not wait on extent conversion to occur, and hence we can return to userspace from a synchronous direct I/O write without having completed all the actions in the write. Hence a read after the write may see zeroes (unwritten extent) rather than the data that was written. Block the I/O completion by triggering a synchronous workqueue flush to ensure that the conversion has occurred before we return to userspace.
