( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/555950?usp=email ) Change subject: Fix possible race when populating pseudo fs ...................................................................... Fix possible race when populating pseudo fs When we create entires in the pseudo fs we create the entry by calling PSEUDO FSAL mkdir. This creates the entrie, but doesn't populate the export junction in the handle. Once we get the handle, we populate the junction, but there could be a race where get get a lookup request for that entry after the mkdir, but before the junction export is updated. We fix this by not returning an entry in the PSEUDO FSAL lookyp while an export update is in progress and the export junction of the handle is NULL. In addition, in order to make sure the handle is fully updated when it is returned, we populate the export junction after every thing else the handle points to is updated.
