Ok. I am also unable to repro the rename program with fanotify example (just FAN_CLOSE_WRITE) on a p9 mount point. Just wondering if you could try git clone operation and can share the results. This can isolate and define the issue precisely. The previous rename trial which failed yesterday was tried on a system where fanotify was initialized by MDE software and the results shared were of the same. Apologies for the confusion.

Ran the fanotify example program(without any changes) on p9 mount point and performed git clone on another session. Git clone was successful. This program was using mask FAN_OPEN_PERM and FAN_CLOSE_WRITE. > 3.) Modified the fanotify example program to mark the mount point using mask FAN_CLOSE_WRITE only. Ran the git clone. The operation fails. I ran the rename_try reproducer only with FAN_CLOSE_WRITE events watched and could not reproduce. > > Is it something to do with mask ? > > I didn't get a chance to run on standard linux kernel.

I am using the 9p mount in the kvm test box that you can download from: https://github.com/tytso/xfstests-bld/blob/master/Documentation/kvm-quickstart.md Thanks, Amir.
