If anyone has any objections, please let me know. ------------------ From: Benjamin Coddington [ Upstream commit 66282ec1cf004c09083c29cb5e49019037937bbd ] Clients must be able to read a file in order to execute it, and for pNFS that means the client needs to be able to perform a LAYOUTGET on the file. This behavior for executable-only files was added for OPEN in commit a043226bc140 "nfsd4: permit read opens of executable-only files". This fixes up xfstests generic/126 on block/scsi layouts.
