xfs: reflink should force the log out if mounted with wsync
Reflink should force the log out to disk if the filesystem was mounted
with wsync, the same as most other operations in xfs.
[Note: XFS_MOUNT_WSYNC is set when the admin mounts the filesystem
with either the 'wsync' or 'sync' mount options, which effectively means
that we're classifying reflink/dedupe as IO operations and making them
synchronous when required.]
