--- Comment #9 from Raghavendra G <rgowdapp at redhat.com> ---
Following is the likely hypothesis:

* readdir-ahead on seeing a write invalidates "attribute" (rest of iatt other
than gfid and ia_type) information keeping "entry" (gfid, ia_type) information,
by zeroing out the iatt corresponding to "attribute" part of iatt.
* Fuse-bridge if it sees zeroed out attribute information, sets
attribute_valid=0 to indicate kernel to consume only entry information and
asking it to do explicit stats for attribute information.

However, on gfapi this option of selectively sending entry information may not
be available and hence the entire iatt is to be invalidated and no inode
information returned (just like readdir).

@Poornima/@niels/@soumya/@Shyam,

How does gfapi handle dentries with zeroed out stats? What information does it
send back to application?
